Rare decays of the B s –meson into four charged leptons in the framework of the Standard Model
In the framework of the Standard Model we present new theoretical predictions for the branching ratios, double and single differential distributions and forward—backward leptonic asymmetries for the B ¯ s → μ + μ − e + e − decay. In our consideration we take into account the ϕ ( 1020 ) —resonance co...
