英文摘要: We present the detailed analytical and numerical investigations of the one-loop radiative corrections of all quarks and their supersymmetric partners in the MSSM to the lightest chargino pair production via gamma gamma fusion at the future NLC. The numerical results show that the cross sections of the subprocess and the parent process are typically enhanced by several per cent compared with the results at the lowest order, and these corrections are mainly contributed by the virtual quarks and squarks of the third generation. Furthermore, we studied the effects induced by the CP-violating complex phases stemming from squark and chargino mass matrices in the MSSM at one-loop level. We find that the radiative corrections are related to all the three CP-violating complex phases phi(t,b) and phi(mu). We conclude that the precise measurement of the cross section and the experimental determination of the parameters phi(mu) and phi(t,b) are crucial in searching for SUSY signals.
