While charged lepton flavor violation (cLFV) with taus is often expected to be largest in many extensions of the Standard Model (SM), it is currently much less constrained than cLFV with electrons and muons. We study the sensitivity of the LHeC to $e$-$tau$ (and $e$-$mu$) conversion processes $p e^- to tau^- + j$ (and $p e^- to mu^- + j$) mediated by a $Z$ with flavor-violating couplings to charged leptons in the $t$-channel. Compared to current tests at the LHC, where cLFV decays of the $Z$ (produced in the s-channel) are searched for, the LHeC has sensitivity to much higher $Z$ masses, up to O(10) TeV. For cLFV with taus, we find that the LHeC sensitivity from the process $p e^- to tau^- + j$ can exceed the current limits from collider and non-collider experiments in the whole considered $Z$ mass range (above $500$ GeV) by more than two orders of magnitude. In particular for extensions of the SM with a heavy $Z$, where direct production at colliders is kinematically suppressed, $e-tau$ conversion at LHeC provides an exciting new discovery channel for this type of new physics.
We study charged lepton flavor violation associated with a light leptophilic axion-like particle (ALP), $X$, at the $B$-factory experiment Belle II. We focus on production of the ALP in the tau decays $tau to X l$ with $l=e,mu$, followed by its decay
We present a comprehensive analysis of the potential sensitivity of the Electron-Ion Collider (EIC) to charged lepton flavor violation (CLFV) in the channel $epto tau X$, within the model-independent framework of the Standard Model Effective Field Th
We investigate the sensitivity of electron-proton ($ep$) colliders for charged lepton flavor violation (cLFV) in an effective theory approach, considering a general effective Lagrangian for the conversion of an electron into a muon or a tau via the e
We study impacts of dimension-five lepton-number violating operators associated with two same-sign weak bosons, $ell^pm ell^{prime pm} W^mp W^mp$, on current and future experiments for neutrino oscillation, lepton-number violating rare processes and
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
