Existence of lepton flavor violation

Ascertain whether lepton flavor violation occurs in nature.

Background

The authors highlight lepton flavor violation (LFV) as a fundamental unresolved question. In the context of their DLRSM analysis, new scalar and gauge interactions can generate LFV couplings, though the paper concentrates on their impact on the muon anomalous magnetic moment rather than on explicit LFV observables.

Despite the model’s capacity to induce LFV, the paper underscores that establishing the existence of LFV remains an outstanding problem beyond the Standard Model, motivating continued experimental searches and theoretical studies.
