2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/42239The current status of the theoretical predictions for the electroweak precision observables M_W, sin^2_theta_eff and m_h within the MSSM is briefly reviewed. The impact of recent electroweak two-loop results to the quantity Delta_rho is analysed and the sensitivity of the electroweak precision observables to the top-quark Yukawa coupling is investigated. Furthermore the level of precision necessary to match the experimental accuracy at the next generation of colliders is discussed.9 pages, 3 figures, contribution to the proceedings of SUSY02, DESY Hamburg, June 2002High Energy Physics - Phenomenologytext
