Abstract

Various mechanisms may contribute to neutrinoless double beta decay in the left-right symmetric model. The interference between these mechanisms also contribute to the overall decay rate. The analysis of the contributions of these interference terms is important for disentangling different mechanisms. In the present paper we study interference effects contributing to the decay rate for neutrinoless double-β\beta decay in the left-right symmetric model. The numerical values for maximum interference for several nuclides are calculated. It is observed that, for most of the interference terms, the contribution is smaller than 20%\% for all the nuclei considered in the study. However, the interference between the mass mechanisms (light and heavy) and η\eta mechanism is observed to be in the range 30%\%-50%\%. The variation of the interference effect with the QQ values is also studied.
