1. Introduction
---------------
All results and input files are available at
http://www.slac.stanford.edu/xorg/hfag/semi/summer03-lp/summer03.shtml
In the following (in no particular order), the updates for LP 2003
with respect to EPS 2003 are discussed.
As usual, most of the error breakdowns can be found in
http://www.slac.stanford.edu/xorg/hfag/semi/summer03-lp/summer03.xls
and
http://www.slac.stanford.edu/xorg/hfag/semi/summer03-lp/summer03.gnumeric
spreadsheets.
2. Changes to common parameters
-------------------------------
We use the updated input parameters for mixing and lifetimes from the
HFAG LP 2003 update. For more information, please see
http://lepbosc.web.cern.ch/LEPBOSC/combined_results/jul12/changes.txt
and
http://lepbosc.web.cern.ch/LEPBOSC/combined_results/jul12/
The changes are:
----------------------------------------------
Parameter LP 2003 EPS 2003
----------------------------------------------
fbd 40.1 +/-1.0 39.0 +/-1.3
tb0 1.536+/-0.014 1.537+/-0.015
tbplus 1.652+/-0.014 1.671+/-0.018
fbs 9.4 +/-1.0 10.1 +/-1.3
fbar 10.4 +/-1.7 11.9 +/-2.0
chi (=chid*f0) 0.091+/-0.004 0.089+/-0.004
----------------------------------------------
The change in fbd is 2.8% with respect to the EPS update (which was
based on the PDG 2003 parameters), but this fbd is the same as used
last year and in the update for the winter 2003 conferences.
3. Changes to averages
----------------------
o Minor correction in the BELLE endpoint result. Included in summary
plot, but not averaged (since nothing in b->ulnu is YET averaged).
