Measurements are reported as a function of q 2 , the square of the dimuon invariant mass and results of the angular analysis are found to be consistent with the Standard Model. In the range 1 < q2 < 6 GeV2/c4 , where precise theoretical calculations are available, the differential branching fraction is found to be more than 3 σ below the Standard Model predictions.37 p.application/pdfengcc-by (c) Garrido Beltrán, Lluis et al., 2015https://creativecommons.org/licenses/by/4.0/HadronsGran Col·lisionador d'HadronsFísica de partículesExperimentsHadronsLarge Hadron Collider (France and Switzerland)Particle physicsExperimentsAngular analysis and differential branching fraction of the decay B {/s 0} → ϕμ + μ -info:eu-repo/semantics/article6567532022-05-19info:eu-repo/semantics/openAccess
