CP-Violating Effects in Two-Body Baryonic Decays of B0-B0 System

  • CP-violating effects in partial-decay-decay-rate asymmetries for two-body baryonic decays of B0-B0 and B0-B0 systems are examined.We concentrate on those final states into which both B0 and B0 can decay.Two cases are discussed in detail:one is for Z0 factory for incoherent BB production,the other is for C=+1 BB production above the Υ(4S) resonance at symmetric colliders.The bb pairs needed for testing these effects are estimated for 3σ signature.For the decay modes B0→PP,Δ++Δ-- and Δ0Δ0,Nbb~107—108.

Abstract: CP-violating effects in partial-decay-decay-rate asymmetries for two-body baryonic decays of B0-B0 and B0-B0 systems are examined.We concentrate on those final states into which both B0 and B0 can decay.Two cases are discussed in detail:one is for Z0 factory for incoherent BB production,the other is for C=+1 BB production above the Υ(4S) resonance at symmetric colliders.The bb pairs needed for testing these effects are estimated for 3σ signature.For the decay modes B0→PP,Δ++Δ-- and Δ0Δ0,Nbb~107—108.
