Description
We revisit the decays $B^- \to \ell^+ \ell^- \bar{\nu}_{\ell'} \ell'^-$ in both $\ell \neq \ell'$ and $\ell = \ell'$ cases. Compared to our previous works, new contributions to decay parameters are investigated. Non-zero lepton masses and interference terms are fully taken into account. Excited resonances are included. The calculations are performed using the orthogonal amplitudes technique. Updated theoretical predictions for branching ratios and differential distributions are presented.
