Precision Tests of the Mssm. *
We present the results of a global fit to the electroweak observables in the MSSM in which, for the first time, all the (relevant) low energy parameters of the model are treated as independent variables. The best fit selects either very low or very large values of tanβ and chargino (higgsino–like) and stop or/and the CP−odd Higgs boson are within the reach of LEP 2. Moreover, the best fit gives...

15 صفحه اولGigaZ: High Precision Tests of the SM and the MSSM
The high-energy eecollider TESLA can be operated in the GigaZ mode on the Z resonance, producing O(10) Z bosons per year. This will allow the measurement of the effective electroweak mixing angle to an accuracy of δ sin θeff ≈ ±1 × 10. Similarly the W boson mass is expected to be measurable with an error of δMW ≈ ±6 MeV near the WW threshold. We discuss the impact of these observables on the ac...
متن کاملHigh-Precision Tests of the MSSM with GigaZ
We review the physics potential of the GigaZ option of the International Linear Collider (ILC) for probing the Minimal Supersymmetric Standard Model (MSSM) via the sensitivity of the electroweak precision observables measured at the ILC to quantum corrections [1]. A particular focus is put on the effective leptonic weak mixing angle, sin θeff . The MSSM predictions take into account the complet...
متن کاملThe MSSM in the Light of Precision Data
The potential of present and anticipated future electroweak precision data, including the Higgs boson and top quark masses, for testing quantum effects of the electroweak theory is investigated in the context of the Minimal Supersymmetric Standard Model (MSSM). The present status of the theoretical predictions is analyzed. The impact of the parametric uncertainties from the experimental errors ...
