Hi Kerstin,
I recently went through the numbers and also made averages for eta l nu
and others. The BF all assume isospin holds, so they have been modified from
the HG_FAG averages.
The D** BF still reflect the set that had 1.4% non-resonant decays,
the newest ones without non-resonant decays are in the presentation I
mailed you,
I hope that this helps,
Vera

Subject: B->Xulnu BFs
Dear vub-recoilers,
if I remember correctly, you more-or-less recently updated the weights
for
the B->Xulnu BFs, but the new files do not seem to have made it into
cvs
yet. I am doing the same on my side by going to the HFAG averages for
the
pi, rho, omega and eta' modes, but I am not sure what to use for eta
(where there are several measurements, but no average from HFAG) and
for
the inclusive BF (I cannot find anything on the HFAG page).
Also, what did you pick for mb and a? B->Xclnu only? B->Xsgamma
only? The
combination? I can basically come up with reasonable justifications for
either of the choices and am wondering what you decided for.
Thanks much,
Kerstin
