Abstract
A search for the fully reconstructed ๐ต0๐
โ ฮผ+ฮผโฮณ decay is performed at the LHCb experiment using proton-proton collisions at ๐ โ
= 13 TeV corresponding to an integrated luminosity of 5.4 fbโ1. No significant signal is found and upper limits on the branching fraction in intervals of the dimuon mass are set
๎ฎ(๐ต0๐ โ๐+๐โ๐พ)<4.2ร10โ8,๎ฎ(๐ต0๐ โ๐+๐โ๐พ)<7.7ร10โ8,๎ฎ(๐ต0๐ โ๐+๐โ๐พ)<4.2ร10โ8,๐(๐+๐โ)โ[2๐๐,1.70]GeV/๐2, ๐(๐+๐โ)โ[1.70,2.88]GeV/๐2,๐(๐+๐โ)โ[3.92,๐๐ต0๐ ]GeV/๐2,
at 95% confidence level. Additionally, upper limits are set on the branching fraction in the [2mฮผ, 1.70] GeV/c2 dimuon mass region excluding the contribution from the intermediate ฯ(1020) meson, and in the region combining all dimuon-mass intervals.
