Multi-leg calculations with the GRACE/1-LOOP system. --Toward Radiative Corrections to e+e- -> mu nu-bar u d-bar --
F. Boudjema, J. Fujimoto, T. Ishikawa +4
We performed the calculation of the full O(alpha) corrections to e+e- -> mu- nu-bar u d-bar with the help of the GRACE/1-LOOP system. We discuss how a finite decay width introduces…
Electroweak corrections to Higgs production through ZZ fusion at the linear collider
F. Boudjema, J. Fujimoto, T. Ishikawa +5
We present the full order alpha electroweak radiative corrections to e+e- -> e+e-H. The computation is performed with the help of GRACE-loop. The extraction of the full QED correct…
Automatic one-loop calculation of MSSM processes with GRACE
J. Fujimoto, T. Ishikawa, M. Jimbo +2
We have developed the system for the automatic computation of cross-sections, {\tt GRACE/SUSY}, including the one-loop calculations for processes of the minimal supersymmetric exte…
GRACE at ONE-LOOP: Automatic calculation of 1-loop diagrams in the electroweak theory with gauge parameter independence checks
G. Belanger, F. Boudjema, J. Fujimoto +4
We describe the main building blocks of a generic automated package for the calculation of Feynman diagrams. These blocks include the generation and creation of a model file, the g…
Full order_alpha electroweak and order alpha_s corrections to e^+e^- --> t t H
G. Belanger, F. Boudjema, J. Fujimoto +5
We present the full electroweak radiative corrections to associated Higgs top pair production in collisions. We combine these results with a new calculation…
Full O(alpha) corrections to e+e- --> nu nu-bar H by GRACE
G. Belanger, F. Boudjema, J. Fujimoto +4
We present the full O(alpha) corrections to single Higgs production in e+e- collision. The computation is performed with the help of GRACE-LOOP where a generalized non-linear gauge…
