Hi all, I checked the effect of B-D reweighting on the Mx and pstar scans. with no reweighting: MX scan ------- all http://www.slac.stanford.edu/~daniele/vub/scansnobd/scanmxnobdmxCut.eps http://www.slac.stanford.edu/~daniele/vub/scansnobd/scanmxnobdmxCutdiff.eps B0 http://www.slac.stanford.edu/~daniele/vub/scansnobd/B0scanmxnobdmxCut.eps http://www.slac.stanford.edu/~daniele/vub/scansnobd/B0scanmxnobdmxCutdiff.eps Bch http://www.slac.stanford.edu/~daniele/vub/scansnobd/BchscanmxnobdmxCut.eps http://www.slac.stanford.edu/~daniele/vub/scansnobd/BchscanmxnobdmxCutdiff.eps Pcms scan --------- all http://www.slac.stanford.edu/~daniele/vub/scansnobd/scanpcmsnobdleptonPCut.eps http://www.slac.stanford.edu/~daniele/vub/scansnobd/scanpcmsnobdleptonPCutdiff.eps B0 http://www.slac.stanford.edu/~daniele/vub/scansnobd/B0scanpcmsnobdleptonPCut.eps http://www.slac.stanford.edu/~daniele/vub/scansnobd/B0scanpcmsnobdleptonPCutdiff$ Bch http://www.slac.stanford.edu/~daniele/vub/scansnobd/BchscanpcmsnobdleptonPCut.eps http://www.slac.stanford.edu/~daniele/vub/scansnobd/BchscanpcmsnobdleptonPCutdiff$ Switching off the BD rewighting does not seem to help... Both B0 and Bch have a bad dependence on pcms. Daniele
