Hi all, here the results of BRBR using a gaus instead of a cb. These numbers are obtained using the chi square fit to the Mx distribution and the new method to calculate the mixing correction on the results of the mes fits on right and wrong sign and not on the histograms (see tomorrow presentation from riccardo). CB: BRBR = 0.0169493 +- 0.00404112(stat) +- 0.00121924(MC stat) GAUSS: BRBR = 0.0171567 +- 0.00435165(stat) +- 0.00127143(MC stat) this implies a difference of 1.2% that will be used as systematics. The systematics related to the signal fit parameters variation (fixed in the mes fits in each Mx bin) will be done ASAP. Daniele
