# Search for the rare decay $\Lambda_{c}^{+} \to p\mu^+\mu^-$

Abstract : A search for the flavor-changing neutral-current decay Λc+→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 B(Λc+→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.
