Predictive CP violating relations for charmless two-body decays of beauty baryons [formula omitted] and [formula omitted] with flavor [formula omitted] symmetry.

Several baryons containing a heavy b-quark have been discovered. The decays of these states provide new platform for testing the standard model (SM). We study CP violation in SM for charmless two-body decays of the flavor SU ( 3 ) anti-triplet beauty baryon (b-baryon) B = ( Ξ b − , Ξ b 0 , Λ b 0 ) in a model independent way. We found, in the flavor SU ( 3 ) symmetry limit, a set of new predictive relations among the branching ratio Br and CP asymmetry A CP for B decays, such as A CP ( Ξ b − → K 0 Ξ − ) / A CP ( Ξ b − → K ¯ 0 Σ − ) = − Br ( Ξ b − → K ¯ 0 Σ − ) / Br ( Ξ b − → K 0 Σ − ) , A CP ( Λ b 0 → π − p ) / A CP ( Ξ b 0 → K − Σ + ) = − Br ( Ξ b 0 → K − Σ + ) τ Λ b 0 / Br ( Λ b 0 → π − p ) τ Ξ b 0 , and A CP ( Λ b 0 → K − p ) / A CP ( Ξ b 0 → π − Σ + ) = − Br ( Ξ b 0 → π − Σ + ) τ Λ b 0 / Br ( Λ b 0 → K − p ) τ Ξ b 0 . Future data from LHCb can test these relations and also other relations found. [ABSTRACT FROM AUTHOR]
