Lepton Flavor Violation at the Large Hadron Collider

Abstract

We investigate a potential of discovering lepton flavor violation (LFV) at the Large Hadron Collider. A sizeable LFV in low energy supersymmetry can be induced by massive right-handed neutrinos, which can explain neutrino oscillations via the seesaw mechanism. We investigate a scenario where the distribution of an invariant mass of two hadronically decaying taus ($\text{tauh}\text{tauh}$) from $\text{schizero}2$ decays is the same in events with or without LFV. We first develop a transfer function using this ditau mass distribution to model the shape of the non-LFV $\text{tauh}\mu$ invariant mass. We then show the feasibility of extracting the LFV $\text{tauh}\mu$ signal. The proposed technique can also be applied for a LFV $\text{tauh}e$ search.
