Differential branching fraction and angular analysis of Λ0b→Λ0μ+μ− decays

O. Leroy

Résumé

The differential branching fraction of the rare decay Λ0b→Λ0μ+μ− is measured as a function of q2, the square of the dimuon invariant mass. The analysis is performed using proton-proton collision data, corresponding to an integrated luminosity of 3.0 fb−1, collected by the LHCb experiment. Evidence of signal is observed in the q2 region below the square of the J/ψ mass. Integrating over 15
