Can the mass of the lightest Higgs boson of the minimal supersymmetric model be larger than mZ?

چکیده
ln the minimal supersymmetric model (MSSM), the tree level -mass of the lightest Higgs scalar h cannot be larger than the mass of the Z boson. We have computed the one-loop radiative correction to the upper bound on m„o as a function of the free parameters of the MSSM. We find that the dominant correction to m„o —mz is large and positive and grows like mi, where m& is the top-quark mass. As a result, the MSSM cannot be ruled out if the CERN e+e collider LEP-200 fails to discover the Higgs boson.

The Supersymmetric Singlet Majoron Model and the General Upper Bound on the Lightest Higgs Boson Mass
An upper bound on the tree-level mass of the lightest Higgs boson of the Supersymmetric Singlet Majoron Model is obtained. Contrary to some recent claims, it is shown to be of the same form as the general mass bound previously calculated for supersymmetric models with an extended Higgs sector. Soft-breaking masses or exotic vacuum expectation values do not enter in the tree-level bound [which i...
متن کاملBosons in the Standard Model and the Minimal Supersymmetric Standard Model
In these lectures we present a brief review of the Higgs boson sector in the Standard Model, and its Minimal Supersymmetric Extension, with particular emphasis on the main mechanisms for Higgs production and decay at LEP2 and LHC, and theoretical bounds on the Higgs boson masses. In the Standard Model the effective potential can develop a non-standard minimum for values of the field much larger...
متن کاملThe Lightest Neutral and Doubly Charged Higgs Bosons of Supersymmetric Left-right Models
We review the phenomenology of light Higgs scalars in supersymmetric left-right models. We consider models with minimal particle content (with and without non-renormalizable higher-dimensional terms) and with additional Higgs superfields. The upper bound on the lightest CP -even neutral Higgs boson in these models is larger than in the minimal supersymmetric standard model, and the Higgs coupli...
متن کاملMass of the lightest supersymmetric Higgs boson beyond the leading logarithm approximation.
We examine the radiative corrections to the mass of the lightest Higgs boson in the minimal supersymmetric extension of the standard model. We use the renormalization-group improved effective potential which includes the next-to-leading-order contributions. We find that, contrary to the result of Espinosa and Quirós, the higher-order corrections to the lightest Higgs boson mass are non-negligib...

This paper is motivated by three issues associated with the supersymmetric extension of the standard model: the μ problem, the possibility of raising the upper bound on the lightest-Higgs-boson mass, and the triviality problem associated with the Higgs sector. A new scheme based on the Higgs-Higgs condensation at low energy is proposed, and it is shown that these three issues are well solved by...
