Calculable Upper Limit on the Mass of the Lightest Higgs Boson in Any Perturbatively Valid Supersymmetric Theory

چکیده
We show that there is a calculable upper limit on the mass of the lightest Higgs boson in any supersymmetric theory that remains perturbative up to a high scale . There are no restrictions on the Higgs sector, or the gauge group or particle content. We estimate the value of the upper limit to be mh◦ < 146 GeV for 100 GeV <∼ Mt <∼ 145 GeV, from all effects except possibly additional heavy fermions beyond top (which could increase the limit by 0-20 GeV if any existed); for Mt >∼ 145 GeV the limit decreases monotonically. We expect to be able to decrease the value of the upper limit by at least a few percent by very careful analysis of the conditions. It is not normal in models for the actual mass to saturate the upper limit.

Particle Mass Limits in Minimal and Nonminimal Supersymmetric Models 1
A review of the Higgs and neutralino sector of supersymmetric models is presented. This includes the upper limit on the mass of the lightest Higgs boson in the Minimal Supersymmetric Standard Model, as well as models based on the Standard Model gauge group SU(2)L U(1)Y with extended Higgs sectors. We then discuss the Higgs sector of left-right supersymmetric models, which conserve R-parity as a...
متن کاملNaturalness Lowers the Upper Bound on the Lightest Higgs boson Mass in Supersymmetry
We quantify the extent to which naturalness is lost as experimental lower bounds on the Higgs boson mass increase, and we compute the natural upper bound on the lightest supersymmetric Higgs boson mass. We find that it would be unnatural for the mass of the lightest supersymmetric Higgs boson to saturate it’s maximal upper bound. In the absence of significant fine-tuning, the lightest Higgs bos...
متن کاملCP–violating Chargino Contributions to the Higgs Coupling to Photon Pairs in the Decoupling Regime of Higgs Sector
In most supersymmetric theories, charginos χ̃±1,2 belong to the class of the lightest supersymmetric particles and the couplings of Higgs bosons to charginos are in general complex so that the CP–violating chargino contributions to the loop–induced coupling of the lightest Higgs boson to photon pairs can be sizable even in the decoupling limit of large pseudoscalar mass mA with only the lightest...
متن کاملPhenomenology of light Higgs bosons in supersymmetric left-right models
We carry out a detailed analysis of the light Higgs bosons in supersymmetric leftright models (SLRM). This includes models with minimal particle content and those with additional Higgs superfields. We also consider models with non-renormalizable higher-dimensional terms. We obtain an upper bound on the mass of the lightest CP -even neutral Higgs boson in these models. The upper bound depends on...
متن کاملThe 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...
