Speaker
Description
In the framework of the Standard Model we present a new theoretical predictions for partial widths, double and single differential distributions for four-leptonic decays of $B_s$ - mesons. We consider the contributions of $φ (1020)$ - resonance, $J/ψ$ - and $ψ(2S)$ - resonances (excluding resonant regions), non-resonance contribution of the $b \bar{b}$ - pairs, leading contribution of “weak annihilation” and bremsstrahlung. We use the model of vector meson dominance for calculation of resonances contributions and take into account a set of new contributions that were not previously considered.
