  1. B+ K+t+t- Status Update August 19th, 2013

  2. Analysis Approach: • HadronicBtag Reconstruction: BSemiExclAdd • Signal MC: 11483 and 11503 • 11483: Generic B+K+t+t-(phasespace) • 11503: B+K+t+t- and B-D0p-, D0K+p-(phasespace) • 11521: Generic B+K+t+t- (Ali Model) • 11520: B+K+t+t- and B-D0p-, D0K+p- (Ali Model) • Consider only 3 track final states, with at most one p0.

  3. Leptonic Modes: • One kaon: Qk=-Qbtag • Two Oppositely charged Leptons (e+e- or m+m-or e+m-) • J/y veto • Sum of 2 leptons does not lie 3.00<Ml+l-<3.194 GeV. • p0 veto • Any 2 clusters with E>30 MeV, 0.1<lateral moment<0.8, Esum>200 MeV and 0.1<Msum<0.16 GeV. • Photon conversions veto • Require sum of e+ with any other oppositely charged track has a mass >50 MeV. • D0 veto • Require sum of Kaon with any oppositely charged lepton does not lie within the mass region 1.80<MK+l-<1.90 GeV.
