A Cosmological Lower Bound on the Higgs Boson Mass
Cosmological considerations imply that the Weinberg-Salam Higgs boson mass mH ) 9 GeV. If this bound were violated, the symmetry breaking phase transition would occur only after extreme supercooling, resulting in too high a ratio of entropy to baryon number.

متن کاملSearching for the intermediate-mass Higgs boson.
We study the feasibility of detecting a neutral Higgs boson Ho, with mass between 2mt w 80 GeV (by assumption) and 2mw at an e+e-machine or the SSC. Backgrounds to the production at an e+e-machine of Ho in association with a Z are calculated with particular emphasis on the case when mH M mz. We present a detailed survey of the signals for and backgrounds to the inclusive or associated productio...
متن کاملMore Signatures of the Intermediate Mass Higgs Boson
We examine the potential signatures of the Higgs boson when it decays into a tau-lepton pair. We show that with the proper identification of the tau-jet, this decay mode can lead to the identification of the Higgs boson over most of the intermediate mass range (MW< MH< 2 MW ).
متن کاملTriviality and the Higgs mass lower bound
In the minimal Standard Model, it is commonly believed that the Higgs mass cannot be too small, otherwise Top quark dynamics makes the Higgs potential unstable. Although this Higgs mass lower bound is relevant for current phenomenology, we show that the Higgs vacuum instability in fact does not exist and only appears when treating incorrectly the cut-off in the renormalization of a trivial theo...
متن کاملRelaxing the Upper Bound on the Mass of the Lightest Supersymmetric Higgs Boson
We present a class of supersymmetric models in which the lightest Higgs-boson mass can be as large as a few hundred GeV (200∼ 300 GeV) while the successful MSSM prediction for gauge coupling unification is preserved. The theories are formulated on a 5D warped space truncated by two branes, and a part of the Higgs sector is localized on the infrared brane. The structure of the Higgs sector in th...
