| Summary: | Title screen We study nuclear µ⁻- E⁻ conversion in the general framework of an effective Lagrangian approach without referring to any specific realization of the physics beyond the Standard Model (SM) responsible for lepton flavor violation (L/f). We show that vector meson exchange between lepton and nucleon currents plays an important role in this process. A new issue of this mechanism is the presence of the strange quark vector current contribution induced by the f meson. This allows us to extract new limits on the L/f lepton–quark effective couplings from the existing experimental data. Режим доступа: по договору с организацией-держателем ресурса |
