2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/43591Recent experimental and theoretical progress in the M_H estimates from M_W and Sin^2_eff_lept is reviewed, with particular emphasis on the role played by M_t. Assuming that the SM is correct and taking into account the lower bound on M_H from direct searches, we derive restrictive bounds on M_W and M_t. We also discuss a representative ``benchmark'' scenario for the possible future evolution of these parameters. Amusingly, this benchmark scenario suggested some time ago a value for M_t that turned out to be in very close agreement with its most recent experimental determination.12 pages, 4 figures, talk given at the Incontri sulla Fisica delle Alte Energie, XVI Ciclo di Incontri, Torino, Italy, April 14-16, 2004High Energy Physics - Phenomenologytext
