Impacts of the bounds on the Higgs mass and m_W on effective theories

Mod.Phys.Lett. A15 (2000) 1377-1384 We study the inter-relations that exist between the present experimental bounds on the Higgs mass, as obtained from radiative corrections to $m_W$, and the effective parameters, $\alpha_i$ and $\Lambda$. We find that the SM bounds on $m_H$, arising from a precise...

Summary:Mod.Phys.Lett. A15 (2000) 1377-1384 We study the inter-relations that exist between the present experimental bounds on the Higgs mass, as obtained from radiative corrections to $m_W$, and the effective parameters, $\alpha_i$ and $\Lambda$. We find that the SM bounds on $m_H$, arising from a precise determination of the $m_W$ mass, can be substantially modified by the presence of dimension-6 operators which appear in the linear realization of the effective Lagrangian approach. A Higgs mass as heavy as 700 GeV can be allowed for scales of new physics of the order of 1 TeV.
