Search for the decay B0 → ϕμ+μ−

Journal of High Energy Physics, vol. 2022

Abstract

Abstract A search for the decayB0→ ϕμ+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 theB0→ ϕμ+μ−decay is found and an upper limit on the branching fraction, excluding theϕand charmonium regions in the dimuon spectrum, of 4.4×10−3at a 90% credibility level, relative to that of the $$ {B}_s^0 $$ Bs0 → ϕμ+μ−decay, is established. Using the measured $$ {B}_s^0 $$ Bs0 → ϕμ+μ−branching fraction and assuming a phase-space model, the absolute branching fraction of the decayB0→ ϕμ+μ−in the fullq2range is determined to be less than 3.2×10−9at a 90% credibility level.
