High-energy cLFV at $\mu$TRISTAN: HNL extensions of the Standard Model

J. Kriewald, E. Pinsard, A. M. Teixeira

Within the context of heavy neutral lepton (HNL) extensions of the Standard Model, we compute the cross-sections for ${\mu }^{+}{e}^{-}\to {\ell }_{\alpha }^{+}{\ell }_{\beta }^{-}$ scattering, as well as several an…
