Hi Kerstin,
I think the currently best BF measurement for B->omegalnu comes from
Belle: (1.3 +/-0.4 +/-0.2 +/-0.3) x 10^-4. This measurement has only 22%
rel. uncertainty, compared to the 100% uncertainty we quote on the
AWG reweighting page, where due to ignorance the omega BF was simply set
equal to the rho0 BF.
We should update all the BF tables on the SL AWG web page soon!
Cheers,
Jochen
