Hoi,
I am looking in recoilDsys.cc at
TRandom rndm(seed);
float xv0[6]={10.2,2.10,4.68,0.,0.63,0.23}; // existing measurements (order: all semilep, D,D*,nothing,D1*,D2*)
float xt0[6]={11.3,2.10,5.60,9.,0.56,0.37};// values from decay.dec
float xe0[6]={0.4,0.19,0.22,0.,0.10,0.08}; // errors on existing measurements
from the HEAD of IBU. I think that these hard-coded numbers should
tell about B0 decays (compared to the tables in files which contain
the D decay numbers), right?
Can someone please explain these numbers? In particular, I am puzzled
about the following:
o How do we get 11.3 from decay.dec? I checked and that should be 10.4
and it is (if you sum it up, e.g. in release 10.3.1a). The existing
measurements for the sl BR B->Xc l nu is 10.42, not 10.2 (PDG)
o I would propose to change 4.68 to 5.4\pm 0.22 since that is the
latest and greatest average from the old LEP-HF working group ([not]
shown in Amsterdam, but implicit in the Vcb's shown there). This is
most probably going to be the new PDG value for the 2003 web update.
Cheers,
--U.
