2018Report
A search for the flavor-changing neutral-current decay $Λ_c^+ → pμ^+ μ^-$ 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 $\mathcal{B}(Λ_c^+ → pμ^+ μ^- ) < 7.7(9.6) × 10^{-8}$ at 90%(95%) confidence level. A significant signal is observed in the $ω$ dimuon mass region for the first time.
