I think we reached a consensus for the BLNP acceptance when using the
Babar HQE fits:
[quoting BobK]
...
\Delta\zeta = 25.04 +4.61 -4.29
from which I find (using a partial BF of 0.87 E-4)
Vub = 4.65 +- 0.24 (stat) +- 0.24 (exp syst)
The BLNP value when using the Belle ellipse is still an open issue. We
quote
\Delta\zeta = 25.31 +/- 4.69 +2.81 -2.69
The central value was from a previous calculation with the Mathematica
notebook, already used at CKM2005, which did not use the exact
translation of the Belle SF parameters values in the SF mass scheme.
Perhaps this has already been discussed during a meeting which I missed,
but is there any reason for not using the acceptance provided by Belle in
their breco Vub paper?
\Delta\zeta = 21.6 +/- 4.0(SF) +2.4 -2.3(theory)
Their paper (hep-ex/0505088) states that the above acceptance (mx<1.7,
q2>8, p*>1) has been calculated using the SF scheme parameters and
correlation, obtained by repeating their b->sgamma analysis with the
predicted shapes of the photon energy distribution from LNP (hep-ex/0504071).
Concezio.
