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?
