Hi all, I would like to encourage you to have a look into hep-ph/0308165, a new paper from Uraltsev and Bigi, concerning a possible bias in the extraction of Lambda from the photon energy spectrum in b->sg. Since <Eg> is a very important ingredient in the extraction of the CLEO's Lambda it might be worthwhile to check by how much the Vub results (and error) change. Given the fact, that there is now also strong evidence that the lepton moment fit from CLEO has underestimated the theoretical errors for P*=1.5, it will be interesting to see the impact of Lambda(1/mb^3) = ~500 MeV (before 390 MeV) l1 (1/mb^3) = -0.3 GeV^2 (before -0.25 GeV^2) on the Vub analysis. As far as correlation and errors are concerned, to first order, you can just keep the CLEO numbers. Please keep also in mined that the above mentioned values are obtained from O(1/mb^3) calculations. You still have to translate them to O(1/mb^2) for your analysis (first order approximation - just shift your Lambda(1/mb^2) by ~100 MeV upwards and l1 by ~50 MeV) Oliver
