Using the precision electroweak data we then determine a lower bound on the scale Λ associated with the underlying new physics. The lower bound on Λ is then used to derive an upper bound on mh through the triviality relation.

The Higgs Boson Mass from Precision Electroweak Data
We present a new global fit to precision electroweak data, including new lowand high-energy data and analyzing the radiative corrections arising from the minimal symmetry breaking sectors of the Standard Model (SM) and its supersymmetric extension (MSSM). It is shown that present data favor a Higgs mass of O(MZ): MH = 76 +152 − 50 GeV We confront our analysis with (meta)stability and perturbati...

متن کاملWhat is the limit on the Higgs mass ? Riccardo
We obtain the bounds on all the gauge invariant, flavour symmetric, CP-even operators of dimension 6 that can affect the electroweak precision tests. For the preferred Higgs mass of about 100GeV, their minimal scales range from 2 to 10 TeV. Depending on the individual operator, these limits are often significantly stronger than those quoted in the literature, when they exist at all. The impact,...

متن کاملHiggs Searches at the Tevatron a
The Higgs boson is the last missing particle in the Standard Model (SM). Its mass is not determined by the SM, there are however several experimental constraints which bound the Higgs mass to values which are within the reach of the Tevatron collider. Lower bounds are given from direct searches at LEP2. These results exclude Higgs masses below 114.4 GeV at the 95% Confidence Level (C.L.) 1. An ...
