- 요약Despite its abundance in extensions to the Standard Model, charged lepton flavor violation (CLFV) has never been observed. In this dissertation, we review some potential avenues for the discovery of CLFV processes. We begin by reviewing the contributions of CLFV scalars to flavorviolating lepton decays and lepton dipole moments, emphasizing their sensitivity to parity-violation (PV) and coupling hierarchies. We then discuss a production mechanism for CLFV particles which is largely independent of PV and coupling hierarchies: on-shell production in experiments involving lepton-nucleus collisions (ℓ −AZ → ℓ '−AZφ). We compare the production cross-sections for (pseudo)scalars and (axial-)vectors for a few benchmark scenarios: SLAC E137, the Electron Ion Collider (EIC), a hypothetical 1 TeV muon beam dump (MuBeD), and a hypothetical 1 TeV Muon (Synchrotron) Ion Collider (MuSIC). We examine the kinematical distributions of the finalstate particles produced at these experiments, and discuss these in relation to detector geometry. We then apply these results to probe a particular class of CLFV scalar: leptophilic axion-like particles (ALPs). We compare these results to limits on the ALP-lepton couplings from Higgs-ALP decays at the LHC, assuming a substantial ALP-Higgs portal interaction. Finally, we explore the possibility of production and subsequent detection of massive gauge bosons for the anomaly-free U(1)Li−Lj symmetries at the EIC, MuBeD, and MuSIC. We also include the analysis for a dark photon and U(1)B−L gauge boson, which, while not explicitly CLFV, serve as useful benchmarks for comparison.
