Consistent Higher-Order Corrections to Stopi -> Sbottomj H+ in the Complex MSSM
Abstract
We review an analysis of a consistent renormalization of the top and bottom quark/squark sector of the MSSM with complex parameters (cMSSM). Various renormalization schemes are defined, analyzed analytically and tested numerically in the decays Stop2 -> Sbottomi H+/W+ (i = 1,2). No scheme is found that produces numerically acceptable results over all the cMSSM parameter space, where problems occur mostly already for real parameters. Some numerical examples for Gamma(Stop2 -> Sbottom1 H+) in our preferred scheme, "mb, Ab DRbar" are shown.
