### 1. Introduction

All results and input files are available at http://www.slac.stanford.edu/xorg/hfag/semi/eps05/eps05.shtml

In the following (in no particular order), the updates for
EPS 2005 with respect to winter conferences 2005 are discussed.

The updates focus on two areas: measurements of exclusive charmless
semileptonic B decays (in particular B -> pi l nu) and measurements
of inclusive charmless semileptonic decays and the determination of
|Vub|.

Note that the information on exclusive charmless semileptonic
B decays has been updated between the
LP 2005 update and this update. The inclusive Vub average
given here is the same as was prepared for LP 2005.

Some of the error breakdowns can be found in
http://www.slac.stanford.edu/xorg/hfag/semi/eps05/eps05.xls
spreadsheet. This has been updated only for inclusive and exclusive |Vub|.

### 2. Changes to common parameters

The parameters used are listed in
common.param;
see the relevant (non-semileptonic) HFAG web pages for how they were determined.

### 3. Average of |Vub| from inclusive measurements on Upsilon(4S)

This determination has changed substantially in the past year. Recent
theoretical developments include radiative corrections to the leading
shape function, studies of sub-leading shape functions, and the
development of a new "generator", i.e. a calculation valid over the
full b -> u l nu decay phase space (see hep-ph/0504071). It is also
widely accepted now that heavy quark (HQ) parameters determined other
processes, e.g. moments from b -> c l nu semileptonic decays, can be
used to constrain moments of the leading shape function.
As the best method for determining the HQ parameters is still
a subject for discussion, |Vub| is determined using several choices
for the HQ parameters.

### 4. B -> pi l nu measurements

Several new measurements are available, some with partial rates in
bins of q^2. The most precise measurements are still the untagged
(i.e. neutrino reconstruction) variety, but the average of the
B-tagged measurements is becoming competitive for the total branching
fraction. The determination of |Vub| from these measurements
is still evolving; the values obtained using some recent form factor
calculations are given.
