QCD corrections to squark production in e + e - Annihilation in the MSSM with complex parameters
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 -\ q̃i q̃j ̄(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. © Springer Science+Business Media, LLC 2007.
