Abstract
A search for the nonresonant Λþ c → pμþμ− decay is performed using proton-proton collision data recorded at a center-of-mass energy of 13 TeV by the LHCb experiment, corresponding to an integrated luminosity of 5.4 fb−1. No evidence for the decay is found in the dimuon invariant-mass regions where the expected contributions of resonances is subdominant. The upper limit on the branching fraction of the Λþ c → pμþμ− decay is determined to be 2.9ð3.2Þ × 10−8 at 90%ð95%Þ confidence level. The branching fractions in the dimuon invariant-mass regions dominated by the η, ρ and ω resonances are also determined.
