Vector mesons in nuclear μ − − e − conversion
نویسنده
چکیده
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 (Lf / ). 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 φ meson. This allows us to extract new limits on the Lf / lepton-quark effective couplings from the existing experimental data. PACS: 12.60.-i, 11.30.Er, 11.30.Fs, 13.10.+q, 23.40.Bw

متن کاملMeson-nucleon Scattering and Vector Mesons in Nuclear Matter *
The electromagnetic decay of the vector mesons into e+e− and μ+μ− pairs makes them particularly well suited for exploring the conditions in dense and hot matter in nuclear collisions. The lepton pairs provide virtually undistorted information on the mass distribution of the vector mesons in the medium. The lepton-pair spectrum in nucleus-nucleus collisions at SPS energies exhibits a low-mass en...
