Hi all, this is a breif update on the neutral and D*0 state. On the D*0 side: a) Run-1 seems validated. you can see http://www.slac.stanford.edu/~asarti/garbage/prova4 and compare with http://www.slac.stanford.edu/~asarti/garbage/prova4 (# of events is slightly different because of a job has crashed: this will be fixed soon) Number of events, and purity will come soon (problem with the argus fit on root). b) Run-2 production has already started on Lyon ! On the neutrals side: Mnu2 plots are starting to look better (means like what was shown by Daniele: http://www.slac.stanford.edu/~asarti/recoil/21112001/Mnu_root.ps ). The prevoius discrepancies were due to missing cuts on the purity of the B in the events and the missing requiremnt of correlation on event charges..) We have studied gammas: Energy, phi and theta. Phi seems to be not promising (flat distributions..) Theta and E are objcet of a deeper study (as preliminary result on theta you can see http://www.slac.stanford.edu/recoil/19112001/ratio_theta_gam.eps) We are planning to look at the combination of Energy and Theta... We want to optimize the resolution of Mx and the quantity: r = #vub / sqrt( #vub + #vcb) But we are waiting for the sideband subtraction.. comments and questions are welcomed, Alessio ______________________________________________________ Alessio Sarti Universita' & I.N.F.N.
