1. Introduction --------------- - All results and input files are available at http://www.slac.stanford.edu/xorg/hfag/semi/pdg08/home.shtml - In the following (in no particular order), the changes with respect to PDG 2007 (web update) are discussed. 2. Changes to common parameters ------------------------------- - New updated values from PDG2008 and HFAG (new mixing and lifetimes values from the HFAG RPP 2008 update of the Oscillations Sub-Group) (common.param). 3. Additions ------------ - Exclusive Branching Fraction: B+ -> D*0lnu - Exclusive Branching Fraction: B+ -> D0lnu - Exclusive Branching Fraction: B- -> D+ pi- lnu - Exclusive Branching Fraction: B- -> D*+ pi- lnu - Exclusive Branching Fraction: B0 -> D0 pi+ lnu - Exclusive Branching Fraction: B0 -> D*0 pi+ lnu - Exclusive Branching Fraction: B- -> D1(D*+pi-)lnu - Exclusive Branching Fraction: B- -> D2(D*+pi-)lnu - Inclusive |Vcb| from global fits - Vub for inclusive and exclusive b->ulnu decays (Vub was not present in previous updates for the PDG). - Two new theoretical interpretations (GGOU and AC) with respect to the results presented at Lepton Photon 2008 are added. - Branching fractions of B0 -> rho- l+ nu 4. Changes ----------- - F(1)|Vcb| and B0 -> D*lnu are obtained from a global fit to the form factors and Vcb. - Asymmetric errors are used for the Vub averages. - Inclusive B->Xlnu decays for determining |Vub| are rescaled to common values of tauB and semileptonic BF (change with respect to Lepton Photon 2007) 5. Feedback ----------- - Your critical comments will be much appreciated. Please send them to lodovico AT slac.stanford.edu
