| Popis: | The neutrino magnetic dipole moment is studied in a simple extension of the SM augmented with a scalar Leptoquark with quantum numbers $(\bar{\boldsymbol{3}},\boldsymbol{1},1/3)$. 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 $(g-2)$, the $\tau \to \mu \gamma$ and the $B_c \to \tau^- \bar \nu$ decay. It is shown that exist a region of the parameter space where the recent anomaly reported by the XENON collaboration can be accommodated. Comment: In preparation for Journal Submission |
