Studying lepton flavor violating μ decays with vector leptoquark
We study the charged LFV μ decays such as μ → e γ , μ → eee , and μ − e Ti 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 th...
