We consider the decay modes of the heavy $q^\prime\bar{q^\prime}$ bound states originating from Higgs boson exchange between quark -- anti-quark pair. In case of a small coupling between the fourth and lower generation the main decay mode…
The presence of the $(B+L)$-conserving decay modes $n \to K^+ e^-,$ $n \to K^+ \mu^-,$ $p \to K^+ e^- \pi^+$ and $p \to K^+ \mu^- \pi^+$ is shown to be a characteristic feature of a class of models with explicit breaking of $R$-parity.…
This paper investigates the beta decay of nuclei within the sd model space, encompassing the $0d_{3/2}$, $0d_{5/2}$, and $1s_{1/2}$ shells. We comprehensively analyze their decay characteristics, including the half-life, $logft$ value, Q…
Nuclear structure plays a significant role on the rapid neutron capture process (r-process) since shapes evolve with the emergence of shells and sub-shells. There was some indication in neighboring nuclei that we might find examples of a…
