Hoi, in the following are a few links to scans for B, B0 and B+. I use the HEAD of IslBrecoilUser (with 'mixcorr 2', which I presume is the new way). Furthermore, I fit with the files contained in inputfiles.dat (in /nfs/farm/babar/AWG7/ISL/tmp/rootfitfiles/lastfiles/.). By default, I get B BRBR = 0.0180181 +- 0.00430567(stat) +- 0.00123682(MC stat) B0 BRBR = 0.00404501 +- 0.00715335(stat) +- 0.00210959(MC stat) B+ BRBR = 0.0277028 +- 0.00544833(stat) +- 0.00179499(MC stat) which is a bit different from this morning's talk. ~ursl/root/ballfit/BALLMX_1.55-MM_0.500.blog is the logfile for this default. Daniele, do you have a logfile against which I can diff? I'd be interested how the difference comes about. MX scan ------- B http://www.slac.stanford.edu/~ursl/talks/070102/BALLMX-stability.eps B0 http://www.slac.stanford.edu/~ursl/talks/070102/BNUMX-stability.eps B+ http://www.slac.stanford.edu/~ursl/talks/070102/BCHMX-stability.eps The total is remarkably stable, but B0 and B+ are anti-correlated (nothing new). MM2 scan -------- B http://www.slac.stanford.edu/~ursl/talks/070102/BALLMM-stability.eps B0 http://www.slac.stanford.edu/~ursl/talks/070102/BNUMM-stability.eps B+ http://www.slac.stanford.edu/~ursl/talks/070102/BCHMM-stability.eps We have a stunning stability of the (B0) result when loosening the cut on mm2. P scan ------- B http://www.slac.stanford.edu/~ursl/talks/070102/BALLP-stability.eps B0 http://www.slac.stanford.edu/~ursl/talks/070102/BNUP-stability.eps B+ http://www.slac.stanford.edu/~ursl/talks/070102/BCHP-stability.eps The sum has been more stable previously, the fluctuations are driven by B+. The B0 result is perfectly stable raising the p* cut to 1.7 GeV. Q = -1 .. +1 ------------ B BRBR = 0.0235617 +- 0.00463323(stat) +- 0.0012843(MC stat) B0 BRBR = 0.0134943 +- 0.00717454(stat) +- 0.00206(MC stat) B+ BRBR = 0.0350774 +- 0.00628954(stat) +- 0.0020162(MC stat) The instability does not improve compared to the default setting. Cheers, --U.
