Limiti di unitarietà sul valore superiore della massa del bosone di Higgs

One-loop corrections to vector boson-vector boson scattering are calculated in the two regimes: high Higgs mass and higher energy and even higher Higgs mass. All possible two-particle channels are considered. One-loop corrections in the scalar sector and with top-bottom doublet inserction are calculated. Constraints from perturbative unitarity are analyzed and discussed
