SUSY Scalar Production in the Electroweak Sudakov Regime of Lepton Colliders
M. Beccaria, M. Melles, F. M. Renard +1
We consider the production of SUSY scalar pairs at lepton colliders, for c.m. energies much larger than the mass of the heaviest SUSY (real or virtual) particle involved in the pro…
High energy behaviour of gamma gamma to f f(bar) processes in SM and MSSM
J. Layssac, F. M. Renard
We compute the leading logarithms electroweak contributions to gamma gamma to f f(bar) processes in SM and MSSM. Several interesting properties are pointed out, such as the importa…
Top Quark Production at TeV Energies as a Potential SUSY Detector
M. Beccaria, S. Prelovsek, F. M. Renard +1
We consider the process of top-antitop production from electron-positron annihilation, for c. m. energies in the few TeV regime, in the MSSM theoretical framework. We show that, at…
The processes gamma gamma to Z H in SM and MSSM
G. J. Gounaris, P. I. Porfyriadis, F. M. Renard
The process gamma gamma to ZH first arises at the 1-loop level, and as such it provides remarkable tests of the structure of the electroweak Higgs sector. These tests are complemen…
The role of universal and non universal Sudakov logarithms in four fermion processes at TeV energies: the one-loop approximation revisited
M. Beccaria, F. M. Renard, C. Verzegnassi
We consider the separate effects on four fermion processes, in the TeV energy range, produced at one loop by Sudakov logarithms of universal and not universal kind, working in the…
