Description |
Left-Right symmetric theories motivated from restoration of parity violation at high scale can also give rise to small neutrino masses naturally through the seesaw mechanism. This also implies violation of lepton number and Majorana nature of neutrinos which can be probed by neutrinoless double beta decay process. In this talk I will discuss the impact of TeV scale left-right symmetric models for neutrinoless double beta decay. We show that in such scenarios a large contribution to the effective mass governing neutrinoless double beta decay can be obtained even if the neutrinos are not quasi-degenerate, thus evading the cosmological bound. |
