Description

We discuss the pair production of scalar quarks in e+ e- annihilation within the MSSM with complex parameters. We calculate the SUSY-QCD corrections to the cross section e+ e- → q-tildeiq-bar-tildej (i, j 1, 2) and show that the effect of the CP phases of these complex parameters on the cross section can be quite strong in a large region of the MSSM parameter space. This could have important implications for squarks searches and the MSSM parameter determination in future collider experiments. (author)
