Search for lepton flavor violation via the intense high-energy muon beam

A deep inerastic scattering process μ N → τ X is discussed to study lepton flavor violation between muons and tau leptons. In supersymmetric models, the Higgs boson mediated diagrams could be important for this reaction. We find that 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 .
