A search for the nonresonant Λ+cpμ+μ decay is performed using proton-proton collision data recorded at a centre-of-mass energy of 13 TeV by the LHCb experiment, corresponding to an integrated luminosity of 5.4 fb1. No evidence for the decay is found in the dimuon invariant-mass regions where the expected contributions of resonances is subdominant. [...]
