Leading two-loop Yukawa corrections to the pole masses of SUSY fermions in the MSSM

Abstract

We have calculated the leading Yukawa corrections to the chargino, neutralino and gluino pole masses in the DR ¯ ′ scheme in the minimal supersymmetric Standard Model (MSSM) with the full set of complex parameters. We have performed a numerical analysis for a particular point in the parameter space and found typical corrections of a few tenths of a percent thus exceeding the experimental resolution as expected at the ILC. We provide a computer program which calculates two-loop pole masses for SUSY fermions with complex parameters up to O ( α α S , Y 4 , α S Y 2 ) .
