Description
Various renormalization schemes are defined, analyzed analytically and
tested numerically in the decays Stop2 -> Sbot_i 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.
Two schemes are identified that show the most robust behavior.
A numerical analysis of the four partial stop}
decay widths is performed in our
``preferred'' scheme, ``m_b, A_b DRbar''.
The full one-loop corrections to the corresponding partial
decay widths are evaluated including hard QED and QCD radiation.
We find mostly modest corrections at the one-loop level.
