Studying lepton flavor violating μ decays with vector leptoquark

Abstract

We study the charged LFV μ decays such as μ → e γ, μ → eee, and μ−eTi with a vector leptoquark (U 3) by considering the constraints from non-standard neutrino interaction (NSI) sector parameter ϵ e μ . We consider that these NSIs are attributed to the presence of leptoquarks to account for the difference in the experimental observations of δ CP measurement by NOvA and T2K. In our study, we obtained the branching ratios with uncertainties for three decay modes: B(μ→eγ)≤4.6−2.6+3.8×10−18,B(μ→eee)≤9.57−5.37+7.43×10−21,Bμ→eTi≤6.89−3.89+5.61×10−19. Our results show an improvement in the current limits, which can be explored in future experiments.
