Lepton Flavor Violation in the Standard Model with dimension 6 operators

Abstract

We investigate Lepton Flavor Violation (LFV) in the general extension of the Standard Model parametrized by the gauge invariant operators of dimension-6. We discuss 3-body charged lepton decays and decay of $Z$ boson to lepton pair and compare the obtained analytical expression with the current experimental results. We derive the numerical bounds on the size of the Wilson coefficients parameterizing the allowed size of New Physics effects.
