We have developed the system for the automatic computation of cross sections, GRACE/SUSY , including the one-loop calculations for processes of the minimal supersymmetric extension of the the standard model. For an application, we investigate the process e + e − → Z 0 h 0 .

We have developed the system for the automatic computation of cross-sections, GRACE/SUSY , including the one-loop calculations for processes of the minimal supersymmetric extension of the the standard model. We discuss how to check our system for the one-loop calculations in comparison with the case for the tree-level calculations. For an application, we investigate the process e + e − → Z 0 h 0 .
متن کاملAlgorithm for the Fermionic Lines in Grace-susy* (revised Version**)
Algorithm of constructing Feynman amplitudes in the framework of minimal supersymmetic extension of the standard model is presented, which can be easily implemented in GRACE, the program of automatic generation of Feynman amplitudes. The equivalence of our method with the prescription given by Denner et al. is proved. 1.Introduction The fundamental theory of elementary particle physics is descr...

Supersymmetry (SUSY) between bosons and fermions at the unification-energy scale is one of the most promising hypothesis, which is expecteted to resolve the remaining problems in the standard model. In particular, the minimal supersymmetric extension of the the standard model (MSSM) [1] has been extensively studied in the last decade due to the simplicity. For more than ten years, we have been ...
متن کاملAutomatic Generation of Tree Amplitudes in the Minimal Supersymmetric Standard Model
GRACE/SUSY is a program package for generating the tree-level amplitude and evaluating the corresponding cross section of processes of the minimal supersymmetric extension of the standard model (MSSM). The Higgs potential adopted in the system, however, is assumed to have a more general form indicated by the two-Higgsdoublet model. This system is an extension of GRACE for the standard model(SM)...
