Long-distance QCD effects in FCNC $B\to \gamma l^{+}{l}^{-}$ decays

Abstract

This presentation reviews the main results of our recent work [A.K., D.M., N.N., Phys. Rev. D97, 053007 (2018)] on rare radiative leptonic decays $B_{d,s}\to \gamma {\mu }^{+}{\mu }^{-}$ and $B_{d,s}\to \gamma e^{+}{e}^{-}$ induced by flavour-changing neutral currents (FCNC) in the Standard Model.
