Neutrinoless Double Beta Decay and <η> Mechanism in the Left-Right Symmetric Model
Abstract
The neutrinoless double beta (0ββ) decay is studied in the framework of left-right symmetric model. The coexistence of left and right handed currents induces rather complicated interactions in the mixing of lepton and hadrons, called <λ> mechanism and <η> mechanism in addition to the conventional effective neutrino mass <m> mechanism. In this letter we indicate the possible magnification of <η> mechanism and importance to survey 0ββ decay of different nuclei for specifying New Physics beyond the Standard Model.
