1. Introduction
---------------
All results and input files are available at

http://www.slac.stanford.edu/xorg/hfag/semi/summer03-eps/summer03.shtml

In the  following (in no particular  order), the updates  for EPS 2003
with  respect  to  PDG  2003  and  the  winter  conferences  2003  are
discussed.

As usual, most of the error breakdowns can be found in

http://www.slac.stanford.edu/xorg/hfag/semi/summer03-eps/summer03.xls

and

2. Changes to common parameters
-------------------------------
We use the input parameters for mixing and lifetimes from the PDG 2003
update.

3. Changes to averages
----------------------

o  Inclusive  semileptonic branching  fraction:  New lepton(?)  tagged
result   from   CLEO   supercedes   the  published   analysis   from
1996. Preliminary  error breakdown  (does not  quite add  up  to the
published systematic, therefore the  "HFAG" systematic error of 0.30
is  a bit  lower  than CLEO's  0.33).  The reference  for the  error
breakdown for this result is M. Artuso, private communication.

The reference  for the error  breakdown for Belle's BRECO  result is
T. Iijima, private communication.

o In the  correction for f+/f0 a mistake had  occurred in the previous
average: The  same relative error  as for the  BF was used;  this is
overestimating the  error by  a factor of  two as |Vcb|*F(1)  is the
sqrt of the BF. This bug  was detected and verified while working on
the inclusion of the BABAR result into the average (which is not yet
contained  in  the EPS  update).   This  bug  is corrected  in  this
update. The resulting change in  the central value of the average is
small (1/5 of  the quoted error). The confidence  level changes from
5.6% to 2.9%.

A  remark to  the plot:  The ellipses  show the  \Delta(\chi^2)  = 1
contours. This is  noted on the plot. The  central values and errors
correspond to the  scaled values that go into  the average. The plot
is therefore a  representation of the (input to  the) average. It is
not intended to show the published results.

A discussion within HFAG has started as to whether we shall increase
the errors  of the experiments  by a similar procedure  described in
PDG 2002.  No conclusion has been  reached, and in  the meantime the
chi^2/dof and the CL are stated  on the plots, so everybody can form
their own impression.

o The same  correction of the error on |Vcb|*G(1)  from f+/f0 as above
has been  corrected. Virtually no  effect here, as it  is negligible
compared to the other errors.

o New result from BELLE on charmless semileptonic B decays in the form
of an endpoint analysis. Included  in summary plot, but not averaged
(since nothing in b->ulnu is yet averaged).
