Delta isobar resonance effects studied by summed isospin spin strengths and nuclear matrix elements for double and single beta decays

Hiroyasu Ejiri

Nuclear matrix elements (NMEs) for double and single beta decays are crucial for studying neutrino properties beyond and within the standard model. The NMEs consist mainly of the s…

Right-handed weak currents in neutrinoless $β β$ decays and ton scale $β β$ detectors

H. Ejiri, T. Fukuyama, T. Sato

Right handed weak-currents (RHCs) in the left-right (L-R) symmetric model for neutrinoless double beta decays (DBDs) of both the $0^{+} \to 0^{+}$ and $0^{+} \to 2^{+}$ transitions are dis…
