New Leptoquark Mechanism of Neutrinoless Double Beta Decay

Abstract
A new mechanism for neutrinoless double beta () decay based on leptoquark exchange is discussed. Due to the specific helicity structure of the effective four-fermion interaction this contribution is strongly enhanced compared to the well-known mass mechanism of decay. As a result the corresponding leptoquark parameters are severely constrained from non-observation of -decay. These constraints are more stringent than those derived from other experiments.
