Hi all,
as consequence of the new "stabilized" version of the mES fit in
VirVubFitter [thanks daniele] the "central" BRBR value has again shifted
[well within the quoted sys]:

Before we were getting ~2.31 (see posting:
http://www.slac.stanford.edu/~asarti/recoil/talks/validation.html),
BRBR = 0.0230708 +- 0.00266732(stat)

and now we fit:
/u/ec/asarti/scra/IbuDefTestDA/DefTestDAresults.dat:
BRBR = 0.0226698 +- 0.00236425(stat) +- 0.000870885(MC stat)

I know that those shifts are disturbing but this is the simple effect of
the changes in the mES technology.

This number should be compared with the other number quoted in the
Validation page
http://www.slac.stanford.edu/~asarti/recoil/talks/validation.html
related to the VubAnalysis code:
BRBR = 0.0229841 +- 0.00274219(stat) +- 0.00100995(MC stat)

Once again the (dis)agreement btw the two results is largely explained by
the uncertainties related to the mES fits.

I'm going now to validate the PRL result by switching back to the PRL
(1-d) reweighting.

Comments or questions are welcomed.

alessio
