Symmetry breaking induced by top quark loops from a model without scalar mass

Abstract

Considering the standard model as an effective electroweak theory, in which we have no scalar mass term in the Higgs potential $({\mu }^2=0)$, we show that the spontaneous symmetry breaking of $SU(2{)}_L\times U(1)$ can be induced by top loops. The Higgs boson mass obtained is smaller than 300 GeV.
