We study the detection of the Higgs bosons predicted in the minimal SUSY standard model (h0, H0, A0 and H±). We find that after radiative corrections are considered, there is a region of parameter space where h0 will be out of the LEP reach. Some portion of this region can be covered at hadron colliders using the mechanism of associated production [Formula: see text], with h0→γγ. Other decays that may help to detect the neutral Higgses (produced either inclusively or in association with [Formula: see text]) are H→ZZ*, W+W−/ZZ, A0→Z+H0. We find that H± may be detected also through the decays H±→W±h0 and the associated production of H± with [Formula: see text].

Mass Reconstruction

The problems of the Standard Model, as well as questions related to Higgs boson properties led to the need to model the ttH associated production and the Higgs boson decay to a top quark pair within the MSSM model. With the help of computer programs MadGraph, Pythia, and Delphes and using the latest kinematic cuts taken from experimental data obtained at the LHC, we have predicted the masses of MSSM Higgs bosons, A and H.

Minimal Supersymmetric Extension

In the context of the minimal supersymmetric extension of the Standard Model, we discuss the impact of the decays of the neutral Higgs bosons into supersymmetric particles, charginos/neutralinos and sfermions. We show that these decay modes could be dominant, when they are kinematically accessible, thus strongly suppressing the branching ratios for the decay channels which are used to detect the Higgs bosons at hadron colliders. These SUSY decay modes should therefore not be overlooked in the search for the Higgs particles at the LHC.

We investigate an extension of the Standard Model with one additional triplet of scalar bosons. Altogether, the model contains four Higgs bosons. We analyze the associated production of the doubly charged scalar with the Standard Model gauge bosons and the remaining Higgs bosons of the model, which are: the light (SM) and heavy neutral scalars and a singly charged scalar. We estimate, in the context of the present (HL–LHC) and future (FCC–hh) hadron colliders, the most promising processes in which a single produced doubly charged Higgs boson is involved.

The ability of future e+e− colliders to study the supersymmetric Higgs sector is examined. The effects of the radiative corrections are included. A global analysis is given for the production cross-sections of the neutral Higgs bosons over the full parameter space of the Higgs sector, which clarifies the integrated luminosity necessary for the detection of the neutral Higgs bosons. The branching ratios of the three neutral Higgs bosons are also computed.

Successful Reduction

AbstractThe search for renormalization group invariant relations among parameters to all orders in perturbation theory constitutes the basis of the reduction of couplings concept. Reduction of couplings can be achieved in certain $$N=1$$ N = 1 supersymmetric grand unified theories and few of them can become even finite at all loops. We review the basic idea, the tools that have been developed as well as the resulting theories in which successful reduction of couplings has been achieved so far. These include: (i) a reduced version of the minimal $$N = 1\ SU(5)$$ N = 1 S U ( 5 ) model, (ii) an all-loop finite $$N = 1\ SU(5)$$ N = 1 S U ( 5 ) model, (iii) a two-loop finite $$N = 1\ SU(3)^3$$ N = 1 S U ( 3 ) 3 model and finally (vi) a reduced version of the Minimal Supersymmetric Standard Model. In this paper we present a number of benchmark scenarios for each model and investigate their observability at existing and future hadron colliders. The heavy supersymmetric spectra featured by each of the above models are found to be beyond the reach of the 14 TeV HL-LHC. It is also found that the reduced version of the MSSM is already ruled out by the LHC searches for heavy neutral MSSM Higgs bosons. In turn the discovery potential of the 100 TeV FCC-hh is investigated and found that large parts of the predicted spectrum of these models can be tested, but the higher mass regions are beyond the reach even of the FCC-hh.

Low Mass

The present constraints from electroweak radiative corrections suggest that the low mass region will be particularly interesting in future Higgs boson searches. In this paper, the discovery potential for a search of a low mass Standard Model Higgs boson, as well as the sensitivity to the lightest Higgs boson of the MSSM (h) are presented as a function of the collected luminosity, for the ATLAS experiment at the LHC.
