Search for the decay $B^0$ → $\phiμ^+μ^–$
Abstract
A search for the decay $B^0$ → $\phiμ^+μ^–$ is performed using proton-proton collisions at centre-of-mass energies of 7, 8, and 13 TeV collected by the LHCb experiment and corresponding to an integrated luminosity of 9 fb –1 . No evidence for the $B^0$ → $\phiμ^+μ^–$ decay is found and an upper limit on the branching fraction, excluding the $\phi$ and charmonium regions in the dimuon spectrum, of 4.4 × 10 –3 at a 90% credibility level, relative to that of the $B^0_s$ → $\phiμ^+μ^–$ branching fraction and assuming a phase-space model, the absolute branching fraction of the $B^0$ → $\phiμ^+μ^–$ in the full q 2 range is determined to be less than 3.2 x 10 –9 at a 90% credibility level.
