Abstract

The neutrino magnetic dipole moment is studied in a simple extension of the SM augmented with a scalar Leptoquark with quantum numbers (3ˉ,1,1/3)(\bar{\boldsymbol{3}},\boldsymbol{1},1/3). In order to reach a sizeable neutrino magnetic moment, we include in the framework the contribution of right-handed neutrinos and analytical result for the one-loop contribution of a scalar LQ is presented. The allowed parameter space is found through recent restrictions on the muon (g2)(g-2), the τμγ\tau \to \mu \gamma and the BcτνˉB_c \to \tau^- \bar \nu decay. It is shown that exist a region of the parameter space where the recent anomaly reported by the XENON collaboration can be accommodated.
