英文摘要:
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 l(i) -> l(j)gamma. 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 --> l(i)(l) over bar (j) and gamma gamma -> l(i)(l) over bar (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.
