	"New Results from SNO"
	The Sudbury Neutrino Observatory (SNO) measures the flux of neutrinos from the Sun using 1000 tons of heavy water (D2O). The heavy water gives SNO exclusive sensitivity to electron neutrinos through a charged current (CC) reaction, as well as the ability to measure all neutrino flavors through a purely neutral current (NC) reaction. In its first phase, SNO rejected the null hypothesis of no neutrino flavor transformation at a level of roughly 5 sigma, by comparing the rates of events from neutrinos of all flavors to the rate for electron neutrinos alone. In its new phase, 2 tons of NaCl were added to the heavy water, enhancing the ability to measure the rate from the neutrinos interacting via the NC reaction. In addition to providing better sensitivity, the NaCl also allowed the measurement of the total flux without assuming the null hypothesis: the energy spectrum of the neutrinos was not needed for the measurement. In the first results from this Phase II, we have measured the total active solar neutrino boron-8 flux with a precision roughly 30% better than our previous measurement. With this higher precision, we find that the measurements point to a large mixing angle but now reject maximal mixing at the 3 sigma level when only SNO data are used, and at over 5 sigma when other solar experiments are included.

	"Time-dependent CP violation in B0 --> phi Ks and related decays at Belle"
	At the XXI Lepton Photon symposium in August 2003, the Belle group presented improved measurements on time-dependent CP asymmetries in the B0 --> phi Ks, eta' Ks and K+ K- Ks decays, which are sensitive to a new CP-violating phase beyond the Standard Model, based on 152 million B-Bbar pairs recorded by July 1, 2003. Belle also updated the CP violation parameter sin2phi_1 with the full data set. In this talk, I will describe the analysis procedures for these results. In the end of my talk, I will briefly explain our plan to upgrade the KEK B factory and discuss sensitivities to physics beyond the Standard Model in the b --> s transition.

	"PID for Super-Belle and Recent Development of Vacuum Photo-Detectors"
	For the future Belle experiment, we have been developing new particle identification devices, based on Cherenkov ring imaging technique; ``TOP (Time-Of-Propagation) counter'' and ``Aerogel RICH''. The TOP counter utilizes internal reflection of Cherenkov photons in a quartz bar, and adopts measurements of the propagation time and the horizontal emission angle of each photon for imaging. The aerogel RICH counter consists of high quality aerogel tiles with refractive index around 1.05 and photodetector plane, which are placed in a proximity focusing geometry. Both detectors require novel photodetectors, having good single-photon sensitivity, position resolution (about 5mm), magnetic field immunity (up to 1.5T) as well as large effective area. The TOP counter requires also superior timing resolution less than 100ps. In this talk, we present the status of our studies for the TOP and aerogel RICH, with emphasis on recent development of Vacuum Photo-detectors, such as multi-anode MCP-PMT and HPD.

	"Measurements of properties of B &rarr K π, π π and KKbar Decays at Belle"
	I will report measuerments of branching fractions for the complete set of B &rarr K π, π π and K K decays, and partial-rate CP asymmetries ACP for the flavor-specific final states K+π-, K+π0, KS0 π+ and π+π0. The properties of these decays provide rich information for the determination of the CKM angles φ3 and φ2. A coherent program of theoretical investigations and improved experimental measurement of the properties of these decays is improtant in order to reduce the hadronic uncertainties and determine the CKM angles. The analysis is based on a data sample of 152 million BB pairs for the B(B0 &rarr π0 π0) and ACP(B0 &rarr K+ π-) measurements and 85 million BB pairs for the other measurements. The data samples were collected at the &upsih(4S) resonance with the Belle detector at the KEKB e+e- storage ring.

	"Detection of Neutrons by Silicon Detectors"
	The talk will be devoted to specific aspects of neutron detection using silicon semiconductor detectors. The speaker will classify neutron induced reactions used for neutron detection as well as neutron reactions with silicon. Special attention will be paid to the development of a position sensitive detector of single neutrons. The concept of such device based on single X-ray photon pixel detector Medipix-1 developed at CERN (64 x 64 square pixels, each 170 &mu m x 170 &mu m) will be presented. Thermal neutrons are converted in a converter layer to heavy charged particles, which are subsequently detected by the Medipix-1 device. Spatial resolution and detection efficiency of such detector will be given for different converter materials (6LiF, 10B) and compared with Monte-Carlo simulations. Device sensitivity to background gamma radiation and to neutron activation will also be mentioned in the talk. Recent tests of such neutron pixel device for neutron radiography and neutron tomography (2D and 3D thermal neutron imaging of real objects) will be shown demonstrating capabilities and possible applications of the device. Plans to improve sensitivity and resolution by adapting a new digital pixel detector system Medipix-2 (256 x 256 square pixels, each 55 &mu m x 55 &mu m) for the single neutron position sensitive detection at high dynamic range will also be given in the talk.

	"Beam polarisation at a future LC: Searches for New Physics"
	A future Linear collider in the energy range of at least sqrt{s}=500 GeV would offer unique possibilities for studying electroweak physics with high precision, such as exploring the mechanism of electroweak symmetry breaking, disentangling the fundamental SUSY parameters, or revealing other kinds of new physics. For these purposes beam polarisation is one of the most powerful tools and it is argued that high polarisation of both the e- beam and the e+ beam is needed. A summary is given of the physics opportunities of running the LC with beam polarisation.

	"Measurement of inclusive hadron production in B-Meson decays with the BaBar detector"
	A measurement of the momentum spectra of charged pions, kaons and protons from B+ and B0 decays will be presented. The data analyzed were taken at the &Upsilon(4S) resonance with the BaBar detector. % at the PEP-II asymmetric B-factory. These hadron spectra were obtained for each B-meson flavor and hadron charge separately. The B-Meson flavor is determined by using fully reconstructed B-meson decays into a flavor eigenstate. The particle types of the charged decay products of the other B-Meson were determined by an algorithm, making use of particle type specific information from various detector components. Multiplicities were extracted and some expected structures were seen, like a peak in the B+ &rarr &pi + spectrum or iso-spin correlations between different pion spectra.

	"Evidence for the Pentaquark: an Exotic Baryon"
	There have been several recent, independent experiments that have announced evidence for a new exotic baryon which is made up of four quarks and one anti-strange quark (flavor structure uudds-bar) at a mass of 1.54 GeV and a narrow width of <10 MeV. This particle is a candidate for the exotic baryon predicted by the chiral soliton model at nearly the same mass. Its narrow width makes it difficult to explain in terms of the conventional quark models, and hence we expect to learn more about non-perturbative QCD in order to explain this particle. Details of the experiments at SPring-8 (in Japan, where it was first seen) and at Jefferson Lab (the CLAS collaboration) will be reviewed. Other experiments showing evidence will be breifly discussed. Some remarks on theoretical developments to explain the $\Theta^+$ will be made.

	The X(3872)
	There are hundreds elementary particles and the discovery of a new one is usually not an extraordinary event. However, as its name is meant to imply, the X(3872) resonance that was recently reported by Belle and confirmned by CDF is peculiar in that it does not easily fit into any known scheme. This state is narrow and is seen in its decay to &pi+ &pi- J/ &psi, which suggests that it is one of the "missing" charmonium states. However, its mass and decay properties do not match well potential model expectations for any of the usual charmonium suspects. The X(3872) also has the intriguing feature that its mass is equal within rather small errors to the sum of the masses of the D 0and D*0 mesons. This suggests that it may not be a q-\bar{q} meson, but is instead a molecular-like D*0\barD b0ound state. In this talk I will present the evidence for the X(3872), describe what we know about its properties in the context of expectations for various possible charmonium states, and discuss strategies for future investigations.

	"Quark Masses, Hyperfine Interaction and Pentaquarks"
	We propose a model for the recently discovered £+ exotic KN resonance as a novel kind of a pentaquark with an unusual color structure: a 3c ud diquark, coupled to 3c ud¹s triquark in a relative P-wave. The state has JP = 1=2+, I = 0 and lies in the antidecuplet of SU(3)f . A rough mass estimate of this pentaquark is close to experiment. We also discuss other related pentaquarks: a ddss¹u exotic ¥, and the anticharmed exotic baryon £c with quark content uudd¹c. We expect that £c is an isosinglet with JP = 1=2¡ and estimate its mass at 2985 § 50 MeV. We also discuss another possible exotic baryon resonance containing heavy quarks, the £+ b , a uudd¹b state, and estimate m£+ b = 6398 § 50 MeV. These states should appear as unexpectedly narrow peaks in D¡p, ¹D 0n, B0p and B+n mass distributions. References: H.J. Lipkin and M. Karliner, hep-ph/0307243 and hep-ph/0307343.

	"Heavy Quarkonia Past, Present, Future"
	Heavy quarkonia continue to be an important laboratory to study aspects of strong interaction. The need for a way to deal with the non-perturbative transitions involved calls for precision measurements on the one hand, and for discovery of as yet undetected states to confirm predictions on the other. The CLEO collaboration is analyzing data recently collected on the Y(1S,2S,3S) as well as psi' and psi(3770) resonances. BES has published results using their large J/Psi and psi' samples. These as well as those from other experiments help to gain a better understanding of the landscape of heavy quarkonia states.

	"Compton Scattering from the Proton in the Hard Scattering Regime"
	This talk will present initial results from JLab E99-114, which studied wide-angle Compton scattering from the proton up to 5.5 GeV. The goal was to distinguish between two theoretical mechanisms for the perturbative subprocess whereby the photons couple to the quarks: Either the subprocess involves three quarks mediated by the exchange of two hard gluons or one quark and no hard gluons. The two mechanisms lead to very different predictions for the scaling of the cross sections both at fixed angle and fixed t and for various polarization observables. A nearly final result for the polarization observables and preliminary results for the unpolarized cross sections will be presented and discussed.

	"Vertex detection in LHCb"
	LHCb will produce B-mesons at high rate to and allows studying CP violation and heavy-quark systems. In addition, precise measurements of B oscillations and CP asymmetries can reveal new physics. Displaced secondary vertices are a special feature of B-meson decays and consequently vertex reconstruction is a fundamental requirement for the LHCb experiment. LHCb places thin silicon strip detectors in the LHC vacuum at only 8 mm distance from the beams. The LHCb detector has been optimized, especially its tracking scheme, to improve the physics performance. The silicon detectors are readout by the Beetle, a deep-submicron frontend chip, specially designed for the vertex detector. The chip is designed to withstand the high radiation levels close to the LHCb interaction point. The frontend amplifier and shaper have strict constraints to cope with the 40 MHz LHC clock. The Beetle chip is bonded to prototype silicon detectors and tested in several testbeam runs at CERN. The current design of the vertex detector meets the LHCb requirements and provides a vertex resolution along the beam direction of about 40 micro-meter to resolve the fast Bs oscillations.

	"MiniBooNE (Mini Booster Neutrino Experiment) at Fermilab will provide a definitive test of the evidence for neutrino oscillations reported by the LSND experiment. The observation of neutrino oscillations with the mass splittings given by the solar, atmospheric and LSND neutrino data cannot be accomodated by the Standard Model with three neutrino mass eigenstates. If confirmed, this mode of neutrino oscillation has tremendous implications for both particle physics and cosmology. We present a status report of the experiment after one year of data taking, including a look at neutrino data and an updated sensitivity analysis."

	"Weak Decay Formfactors - Theory and Applications"
	The measurement of B decays to final states involving a light meson (i.e. pi, rho, K, K*) is very relevant for determining CKM-matrix elements and clarifying the question if CP-violation is indeed due to one complex phase in that matrix or if there are new sources of CP-violation beyond the Standard Model. The reliable extraction of weak parameters necessitates sufficient control of QCD-effects. I describe new results for the relevant decay form factors, in from QCD sum rules on the light-cone, and discuss the strength and limitations of that approach.

	The Tevatron collider experiments are currently in a unique position to observe new phenomena. While optimizing for a major discovery is complicated by an overabundance of theoretical possibilities, exploiting common phenomenological themes and experimental strengths leads to carefully focused improvements in detector hardware, reconstruction techniques and search strategies that maximize th physics potential of the CDF experiment. The elements of this approach include a new silicon detector with increased coverage and improved impact-parameter resolution, a novel high-acceptance tracking algorithm for electrons and a program of signature-based searches for new physics. Preliminary results from this program will be presented: a search for new physics in the spectrum of high-mass electron pairs.

	"Double Beta Decays and Solar Neutrinos by MOON(Mo Observatory Of Neutrinos)"
	The MOON (Molybdenum Observatory Of Neutrinos) project is a hybrid double-beta and solar neutrino experiment with 100Mo. It aims at high sensitive studies of double beta decays with a neutrino mass sensitivity of 0.03 eV and real-time studies of pp and 7Be solar neutrino's. The double beta rays from 100Mo are measured in prompt coincidence for the neutrinoless double beta decays and the inverse beta rays from solar-neutrino captures of 100Mo are measured in delayed coincidence with the subsequent beta decay of 100Tc. One option of the MOON detector is a supermodule of x-y scintillation fiber planes and scintillation plates. Thin100Mo films are interleaved between the fiber planes. Measurements with good position resolution enable one to select true signals by spatial and time correlations. A proto type MOON detector, MOON-1, is under construction.
