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

Fabiola Fortuna, Gerardo HernÃ¡ndez-TomÃ©, Diego Portillo-SÃ¡nchez +1

We study the four-body heavy baryon decay, including two leptons in the final state, of the form $B_{A} \to B_{B} P ℓ_{I^} \pm ℓ_{I^}^{2}$ , which can be either a lepton number conserving (LNC…

Proton-box contribution to $a_{I^} ¼^{HLbL}$

Emilio J. Estrada, Juan Manuel MÃ¡rquez, Diego Portillo-SÃ¡nchez +1

We analyze the proton $-$ box contribution to the hadronic light $-$ by $-$ light part of the muon's anomalous magnetic moment, which is the first reported baryonic…

Authentic Majorana versus singlet Dirac neutrino contributions to $I^¼^{+} I^¼^{+} \to ℓ^{+} ℓ^{+}$ $(ℓ = e, I ¨ )$ transitions

We revisited the computation of the cross section for the $I^¼^{+} I^¼^{+} \to ℓ^{+} ℓ^{+}$ $(ℓ^{+} = I ¨ ^{+}, e^{+})$ transitions in the presence of new heavy Majorana neutrinos. We focus…
