Abstract

The first observation of the Cabibbo-suppressed decay V⁰_b → J/ψpπ⁻ is reported using a data sample of proton-proton collisions at 7 and 8TeV, corresponding to an integrated luminosity of 3 fb⁻¹. A prominent signal is observed and the branching fraction relative to the decay mode V⁰_b → J/ψpK⁻ is determined to be B[Equations Found] A search for direct CP violation is performed. The difference in the CP asymmetries between these two decays is found to be [Equations Found], which is compatible with CP symmetry at the 2.2σ level.
