Two-Loop Results for M_W in the Standard Model and the MSSM
Ayres Freitas, Sven Heinemeyer, Georg Weiglein
Recent higher-order results for the prediction of the W-boson mass, M_W, within the Standard Model are reviewed and an estimate of the remaining theoretical uncertainties of the el…
Sfermion Precision Measurements at a Linear Collider
A. Freitas, J. Kalinowski, B. Ananthanarayan +27
At future e+- e- linear colliders, the event rates and clean signals of scalar fermion production - in particular for the scalar leptons - allow very precise measurements of their…
Reconstruction of Fundamental SUSY Parameters
P. M. Zerwas, J. Kalinowski, A. Freitas +5
We summarize methods and expected accuracies in determining the basic low-energy SUSY parameters from experiments at future ee linear colliders in the TeV energy range, com…
Precise predictions for slepton pair production
Ayres Freitas, Andreas v. Manteuffel
At a future linear collider, the masses and couplings of scalar leptons can be measured with high accuracy, thus requiring precise theoretical predictions for the relevant processe…
Gauge dependence and renormalization of tan(beta)
Ayres Freitas, Dominik Stöckinger
Renormalization schemes for tan(beta) are discussed in view of their gauge dependence. It is shown that several common renormalization schemes lead to a gauge-dependent definition…
Gauge dependence and renormalization of in the MSSM
Ayres Freitas, Dominik Stöckinger
Well-known and newly developed renormalization schemes for are analyzed in view of three desirable properties: gauge independence, process independence, and numerical stabi…
