Vilkovisky-DeWitt Effective Potential and the Higgs-Mass Bound
Guey-Lin Lin, Tzuu-Kang Chyi
Abstract
We compute the Vilkovisky-DeWitt effective potential of a simplified version of the Standard Electroweak Model, where all charged boson fields as well as the bottom-quark field are neglected. The effective potential obtained in this formalism is gauge-independent. We derive from the effective potential the mass bound of the Higgs boson. The result is compared to its counterpart obtained from the ordinary effective potential.
