Hi all, in order to check the stability of the fit result as a function of the MX cut, I tried to fit the contribution of D**,D1,2, nres contribution. I replaced the "other" contribution with D**,D1,2, nres + other. An example of the fit is in http://www.slac.stanford.edu/~daniele/vub/scanDdouble/fitDss.eps The number I get is unchanged with respect to the default one. These are the scans All http://www.slac.stanford.edu/~daniele/vub/scanDdouble/mxfinaltestdssmxCut.eps http://www.slac.stanford.edu/~daniele/vub/scanDdouble/mxfinaltestdssmxCutdiff.eps B0 http://www.slac.stanford.edu/~daniele/vub/scanDdouble/mxfinalB0testdssmxCut.eps http://www.slac.stanford.edu/~daniele/vub/scanDdouble/mxfinalB0testdssmxCutdiff.eps Bch http://www.slac.stanford.edu/~daniele/vub/scanDdouble/mxfinalBchtestdssmxCut.eps http://www.slac.stanford.edu/~daniele/vub/scanDdouble/mxfinalBchtestdssmxCutdiff.eps No improvement in the B0 scan.
