Rare four leptonic B-mesons decays with a neutrino in final state

Abstract

We revisit prediction for the four – leptonic decay of charged B - mesons in the Standard Model and provide an updated results for branching ratios and various differential distributions. We have taken into account relative phase between intermediate ρ0(770) – and ω(782) – resonances contributing to the amplitude in the framework Vector Meson Dominance model approach.
