Contribution
It introduces a comprehensive method for calculating 1-loop decay widths of sparticles with an automated tool and detailed renormalization scheme in the MSSM.
Findings
Numerical decay widths for sfermions and gluino are provided.
The renormalization scheme ensures consistent 1-loop calculations.
Results depend on different SUSY parameter sets.
Abstract
The 1-loop corrected decay widths of sparticles (charginos, neutralinos, gluino and sfermions) in the framework of the MSSM are calculated systematically using GRACE/SUSY-loop, which is the program package for the automatic calculation of the MSSM amplitudes in the 1-loop order. We present the renormalization scheme used in our system and show some numerical results of decay widths of sfermions and gluino using the SPS1a' parameter set and other SUSY parameter sets.
