DESCRIPTION:Speakers: Dmitrii Ostapovich (P.N. Lebedev Physics Institute)\
 nWe revisit the decays $B^- \\to \\ell^+ \\ell^- \\bar{\\nu}_{\\ell'} \\el
 l'^-$ in both $\\ell \\neq \\ell'$ and $\\ell = \\ell'$ cases. Compared to
  our previous works\, new contributions to decay parameters are investigat
 ed. Non-zero lepton masses and interference terms are fully taken into acc
 ount. Excited resonances are included. The calculations are performed usin
 g the orthogonal amplitudes technique. Updated theoretical predictions for
  branching ratios and differential distributions are presented.\n\nhttps:/
