Ciao Concezio, the motivation for those choices for the BFs can be found
on the last table in:
http://www.slac.stanford.edu/~lodovico/protected/vub/weights/hybrid.html
with respect to which only the pi/pi0lnu BFs have been updated to the
PDG07 (HFAG averages).
The central values for mb and a comes from hep-ex/0507253 (Oliver's and
Henning's paper), see the first line below the first table.
I will update the web page with the new weights once ready.
I thought this was the decision we reached at the meeting last week, if
not, could you please let me know what should I change?
Thanks,
Francesca
