BReco Meeting 07/08/044 Overview of Pentaquark Searches Same minimal quark content as in direct combination of channels 3-4 (cbaruuud) may be obtained with D* - (D - )p  + in channels 1-2

BReco Meeting 07/08/046 Final Cuts Subdivided into channel independent and channel dependent cuts Coupled to branching ratio extraction analysis Documented in BAD 916 (branching ratio extraction analysis)  BAD 997 to be submitted today  Continuation of BAD 916 Today’s talk by Xin Chen

BReco Meeting 07/08/047 Constrained Mass for Channels 1-2 D 0 ->K  D 0 ->K3  D 0 ->K  0 D - ->K -  +  + Channel 1 (B 0 ->D*  ppbar , D*->D 0  ) Channel 2 (B 0 ->D  ppbar  )

BReco Meeting 07/08/0416 Upcoming Analyses Need to look more into D *0 (D 0 )p invariant mass spectra  Exclusive decays (not observed before)  B - ->D *0 ppbar  - (plus c.c.)  B - ->D 0 ppbar  - (plus c.c.)  Beta Ntuples have been generated. To be analyzed  Hard for a 4 GeV resonance due to lack of phase space  Inclusive analysis  D* 0 p (plus c.c.)  D 0 p (plus c.c.)  Beta Ntuples have been generated. To be analyzed

BReco Meeting 07/08/0417 Outlook and Plans Search of a charmed pentaquark in B 0 ->D ( * ) ppbar(  ) decays is reaching maturity  BAD 916 v5 with details on branching ratio (for all 4 B decays) has been submitted  Will submit BAD 997, continuation of BAD 916 with details of pentquark analysis  In channels 1 and 2 Dp invariant mass spectra do not show significant deviation from phase-space hypothesis  Channels 3 and 4 display differences between D0*barp (direct combination) and D0*p (indirect combination) invariant mass spectra, inconsistent with MC prediction  Will start looking into  Exclusive decays B - ->D *0 ppbar  -, B - ->D 0 ppbar  - (plus c.c.)  Inclusive D* 0 p and D 0 p (plus c.c.)
