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 electroweak constraints. All have unusual features, and all can be distinguished from the Minimal…

Precision electroweak analysis after the Higgs boson discovery

Until recently precision electroweak computations were fundamentally uncertain due to lack of knowledge about the existence of the Standard Model Higgs boson and its mass. For this reason substantial

Probing heavy Higgs boson models with a TeV linear collider

The last years have seen a great development in our understanding of particle physics at the weak scale. Precision electroweak observables have played a key role in this process and their values are

Naturalness bounds in extensions of the MSSM without a light Higgs boson

Adopting a bottom-up point of view, we make a comparative study of the simplest extensions of the MSSM with extra tree level contributions to the lightest Higgs boson mass. We show to what extent a

Beautiful mirrors and precision electroweak data

The standard model (SM) with a light Higgs boson provides a very good description of the precision electroweak observable data coming from the CERN LEP, SLD and Fermilab Tevatron experiments. Most of

Dark Higgs models at the 7 TeV LHC

A bstractWe study how collider data and electroweak precision observables affect the parameter space of models including a new dark force mediated by a massive U(1) gauge boson. It acquires mass via

Improved naturalness with a heavy Higgs boson: An alternative road to CERN LHC physics

The quadratic divergences of the Higgs mass may be cancelled either accidentally or by the exchange of some new particles. Alternatively its impact on naturalness may be weakened by raising the Higgs

CONSTRAINING NEW MODELS WITH PRECISION ELECTROWEAK DATA

Electroweak precision data have been extensively used to constrain models containing physics beyond that of the Standard Model (SM). When the model contains Higgs scalars in representations other

Virtual effects of light gauginos and Higgsinos: A precision electroweak analysis of split supersymmetry

We compute corrections to precision electroweak observables in supersymmetry in the limit that scalar superpartners are very massive and decoupled. This leaves charginos and neutralinos and a

Higgs boson decay into hadronic jets

The remarkable agreement of electroweak data with standard model (SM) predictions motivates the study of extensions of the SM in which the Higgs boson is light and couples in a standard way to the

Limits on a composite Higgs boson.

A fit to precision electroweak data is performed and it is found that a Higgs mass up to 500 GeV is allowed.

The Higgs mass and new physics scales in the minimal standard model

We study the theoretical correlation between the Higgs mass of the minimal standard model and the scale at which new physics is expected to occur. In addition to the classic constraints of unitarity,

Electroweak precision measurements and collider probes of the standard model with large extra dimensions

The elementary particles of the standard model may reside in more than 3+1 dimensions. We study the consequences of large compactified dimensions on scattering and decay observables at high-energy

What is the limit on the Higgs mass

Calculable upper limit on the mass of the lightest Higgs boson in perturbatively valid supersymmetric theories with arbitrary Higgs sectors.

A calculable upper limit on the mass of the lightest Higgs boson is derived in perturbatively valid supersymmetric theories with arbitrary Higgs sectors with standard model gauge symmetry and a supersymmetry spectrum around or below 1 TeV.
