Description

Lepton flavor violation (LFV) is a suitable avenue to look for physics beyond the SM. The observation of neutrino oscillation has opened a new window, indicating new physics. In our work, we study the charged LFV $\mu$ decays such as $\mu\rightarrow e\gamma$, $\mu \rightarrow eee$, and $(\mu - e)_{\text{Ti}}$ with a vector leptoquark ($U_3$) by considering the constraints from non-standard neutrino interaction (NSI) sector parameter $\epsilon_{e\mu}$. We consider that these NSIs are attributed to the presence of leptoquarks to account for the difference in the experimental observations of $\delta_{CP}$ measurement by NOvA and T2K. We obtained the branching ratios with uncertainties for three decay modes: $(\mu \rightarrow e \gamma) \leq 10^{-18}$, $(\mu \rightarrow eee) \leq 10^{-21}$ and $(\mu \rightarrow e)_{\text{Ti}} \leq 10^{-19}$.Our results show an improvement in the current limits, which can be explored in the future experiments.
