Bounds on M_W, M_t, Sin^2 theta_eff^lept
arXiv:hep-ph/0401196
Abstract
Assuming that the Standard Model is correct and taking into account the lower bound on M_H from direct searches, we discuss bounds on M_W, M_top, and Sin^2 theta_eff_lept at various confidence levels. This permits to identify theoretically favored ranges for these important parameters in the Standard Model framework, regardless of other observables. As an illustration of possible future developments, a hypothetical benchmark scenario, involving shifts less then 1 sigma in the experimental central values, is discussed.
