Lepton number violating and conserving heavy baryon four-body decays in the presence of two almost degenerate heavy neutrinos

Fabiola Fortuna, Gerardo Hernández-Tomé, Diego Portillo-Sánchez +1

We study the four-body heavy baryon decay, including two leptons in the final state, of the form $B_A\to B_{B}P{\ell }_{\alpha }{\ell }_{\beta }$, which can be either a lepton number conserving (LNC)…
