Abstract

We discuss a deep inerastic scattering process μN→τX to study lepton flavor violation between muons and tau leptons. In supersymmetric models, the Higgs boson mediated diagrams could be important. At a muon energy (E_μ) higher than 50 GeV, the predicted cross section significantly increases due to the contribution from sea b-quarks. The number of produced tau leptons can be O(10^4) at E_μ=300 GeV from 10^<20> muons, whereas O(10^2) events are given at E_μ=50 GeV. Another promising possibility to search for the eN→τX reaction at an electron-positron linear collider is also discussed. Searches for these reactions would be competitive with studies of rare tau decays and have potential to improve sensitivities to lepton flavor violation significantly.
