Hi Concezio, in view of the comments from Gil Paz, Steve Playfer, Roberto and myself would like to make the following proposal for the changes to the hep-ex paper. - pag 18. "For the BLNP calculations the two sets of shape function parameters are in good agreement and thus give consistent results on \Vub. However, there are concerns that the extraction of the shape function parameters from the photon spectrum in \Bsg is less reliable." should be replaced with: "For the BLNP calculations the two sets of shape function parameters coming from a fit to the photon energy spectrum and to the b->clnu moments are in good agreement and thus give consistent results on \Vub." (the next sentence doesnt seem to be justified so it has to be taken out) As already noticed, the results from the fit to the spectrum are both supported by the authors of the BLNP theory and also are consistent with the ones from the fit to the b->clnu moments (as can be seen in Colin's talk at EPS). Please let us know if you need further discussion on this topic. Roberto, Steve and Francesca
