The search for lepton-flavor-violation process e^+e^-\to e\mu in the energy region \sqrt{s}=984 - 1060 MeV with SND detector at VEPP-2M e^+e^- collider is reported. The model independent 90% CL upper limits on the e^+e^-\to e\mu cross section, \sigma_{e\mu} < 11 pb, as well as on the corresponding \phi\to e\mu branching fraction, B(\phi\to e\mu) < 2 \times 10^{-6}, for the final particles polar angles 55^\circ<\theta<125^\circ, were obtained.

  1. Revisiting lepton flavor violation: $\tau$ and meson decays

    hep-ph 2025-11 unverdicted novelty 3.0

    Updated type-I seesaw analysis shows semileptonic tau decays like tau to lepton rho can dominate cLFV signals and some branching ratios may reach next-generation experiment sensitivity.
