For heavy top-quark masses, lower bounds on mH are also obtained. The importance of including two-loop electroweak corrections and Consoli–Hollik–Jegerlehner resummation in obtaining these bounds on mH is emphasized. The present analysis incorporates these leading two-loop electroweak corrections ...
