[Bfys-physics] News flash: fs/fd vs pt
by Niels Tuning 11 Oct '12

11 Oct '12

Dear all, Let me advertise a fresh result from Rose and Barbara! Yesterday they unblinded their result for any pt or eta dependence for fs/fd (see att.). It seems there is some trend, which can have implications for the BR limit on Bs->mumu at CMS. This afternoon there is a short report in the B2OC WG, and tomorrow at 16:00 we will have the approval-to-go-to-paper presentation for LHCb. Cheers, Rose, Barbara, Niels ---------- Forwarded message ---------- Date: Wed, 10 Oct 2012 19:58:03 +0000 From: Barbara Storaci <Barbara.Storaci(a)cern.ch> To: "lhcb-phys-cp-measurements-trees (LHCb mailing list for physics phys-cp-me asurements-trees)" <lhcb-phys-cp-measurements-trees(a)cern.ch>, "lhcb-review-B2OC-fsfdHad2011 (lhcb-review-B2OC-fsfdHad2011)" <lhcb-review-B2OC-fsfdHad2011(a)cern.ch> Cc: Aurelien Martens <aurelien.martens(a)lpnhe.in2p3.fr>, Cristina Lazzeroni <Cristina.Lazzeroni(a)cern.ch> Subject: Unblided results for the fs/fd dependency as a function of pt and eta Dear Members of the WG, today we unblided our data and we presented the results of the dependence of fs/fd as a function of pt and eta. In attachment you can find the plots. Tomorrow at the WG meeting we can discuss the result, if you think it can be useful, before the approval presentation on Friday. Notice few things about the plot: * no correlated error in the point error bars -> still to be added to the p0 parameter error, but not affecting the slope * new value used for Nf (Nf = 1.092 +- 0.093) Enjoy the plots, especially the pt one ;-) Cheers, Barbara, Laurence, Niels, Nico, Rose
