The Lepton-Number-Violating Decays of $B^+, D^+ $ and $D_s^+$ Mesons Induced by the Doubly Charged Higgs Boson

TL;DR

This paper investigates lepton-number-violating decays of certain mesons induced by a doubly charged Higgs boson, finding results consistent with previous models but with smaller predicted branching ratios.

Contribution

It introduces a study of meson decays mediated by a doubly charged Higgs, extending previous work to include this new particle's effects.

Findings

Branch ratios are smaller than current experimental limits.

Results align with previous relativistic quark model calculations.

Decays proceed via the light Majorana neutrinos.

Abstract

The lepton-number-violating decays of $B^+, D^+$ and $D_s^+$ mesons induced by the doubly charged Higgs boson have been studied. It is found that although the yielded results of the branch ratio are much smaller than the present limits from the data they are consistent with the previous conclusions calculated in the framwork of relativistic quark model where the processes happened via the light Majorana neutrinos.
