Abstract

Measurements of the differential branching fraction and angular moments of the decay B⁰ → K⁺π⁻μ⁺μ⁻ in the K⁺π⁻ invariant mass range 1330 < m(K⁺π⁻) < 1530 MeV/c² are presented. Proton-proton collision data are used, corresponding to an integrated luminosity of 3 fb⁻¹ collected by the LHCb experiment. Differential branching fraction measurements are reported in five bins of the invariant mass squared of the dimuon system, q², between 0.1 and 8.0 GeV²/c⁴. For the first time, an angular analysis sensitive to the S-, P- and D-wave contributions of this rare decay is performed. The set of 40 normalised angular moments describing the decay is presented for the q² range 1.1-6.0 GeV²/c⁴.
