The Higgs Boson Mass from Precision Electroweak Data
نویسنده
چکیده
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 perturbative bounds on the SM Higgs mass, and the theoretical upper bound on the MSSM Higgs mass. Present data do not discriminate significantly between the SM and MSSM Higgs mass ranges. We comment in passing on the sensitivity of the Higgs mass determination to the values of α(MZ) and αs(MZ).

Higgs Boson Searches at LEP 2
In this talk preliminary results of Higgs boson searches at LEP2 up to centre-of-mass energies of 183 GeV have been summarised. The main topics are searches for the Minimal Standard Model (MSM) Higgs boson and searches for neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM). No indication for Higgs production has been found. The experiments have published their Higgs search...
متن کاملElectroweak Precision Data Global Higgs Analysis
The status of published and preliminary precision electroweak measurements as of winter 2002/03 is presented. The new results on the mass of the W boson as measured at LEP-2 and on atomic parity violation in Caesium are included. The experimental results are compared with the predictions of the minimal Standard Model and are used to constrain its parameters, including the mass of the Higgs boso...
متن کاملLimits on the Mass of a Composite Higgs Boson
Current results from the LEP Electroweak Working Group2,3 favor a Higgs boson mass that is relatively light. The “best-fit” value for the Higgs mass is somewhat less than experimental lower bound of 107.7 GeV reported at this conference.4 The 68% and 95% CL upper bounds from precision measurements, in the context of the standard model, are 127 and 188 GeV respectively. It is possible that, as t...
متن کاملHiggs-mass predictions and electroweak precision observables in the Standard Model and the MSSM∗
Higher-order results for electroweak precision observables in the Standard Model are analyzed in view of the experimental accuracies achievable at the present and the next generation of colliders, and the indirect prediction of the Higgs-boson mass from the precision data is discussed. Within the MSSM, two-loop results for the lightest CP-even Higgs-boson mass are confronted with the exclusion ...
متن کاملElectroweak Precision Physics from Low to High Energies
Electroweak precision observables (EWPO) can give valuable information about the last unknown paramter of the Standard Model (SM), the Higgs-boson mass M H . EWPO can also restrict the parameter space of new physics models (NPM) such as the Minimal Supersymmetric Standard Model (MSSM). We review the respective constraints from the W boson mass, the effective leptonic mixing angle, the anomalous...
متن کاملHow Can a Heavy Higgs Boson be Consistent with the Precision Electroweak Measurements?
The fit of precision electroweak data to the Minimal Standard Model currently gives an upper limit on the Higgs boson mass of 170 GeV at 95% confidence. Nevertheless, it is often said that the Higgs boson could be much heavier in more general models. In this paper, we critically review models that have been proposed in the literature that allow a heavy Higgs boson consistent with the precision ...
