Lepton flavor-changing processes in R-parity violating MSSM: Z→ℓiℓ¯j and γγ→ℓiℓ¯j under new bounds from ℓi→ℓjγ

We examine the lepton flavor-changing processes in R-parity violating MSSM. First, we update the constraints on the relevant R-violating couplings by using the latest data on the rare decays ℓi→ℓjγ. We find that the updated constraints are much stronger than the old ones from rare Z-decays at LEP. Then we calculate the processes Z→ℓiℓ¯j and γγ→ℓiℓ¯j. We find that with the updated constraints the R-violating couplings can still enhance the rates of these processes to the sensitivity of GigaZ and photon-photon collision options of the ILC.
