| Abstract: | A search for the flavor-changing neutral-current decay Λ + c → p μ + μ − is reported using a data set corresponding to an integrated luminosity of 3.0 fb − 1 collected by the LHCb Collaboration. No significant signal is observed outside of the dimuon mass regions around the ϕ and ω resonances, and an upper limit is placed on the branching fraction of B ( Λ + c → p μ + μ − ) < 7.7 ( 9.6 ) × 10 − 8 at 90%(95%) confidence level. A significant signal is observed in the ω dimuon mass region for the first time. |
