We study the production sensitivity of Higgs bosons h and H, in relation to the possible existence of Z′ boson and a top quark pair at the energy scales that will be reached in the near future at projected e+e- linear colliders. We focus on the resonance and no-resonance effects of the annihilation processes e+e-→(γ,Z,Z′)→tt-h and e+e-→(γ,Z,Z′)→tt-H. Furthermore, we develop and present novel analytical formulas to assess the total cross section involved in the production of Higgs bosons. We find that the possibility of performing precision measurements for the Higgs bosons h and H and for the Z′ boson is very promising at future e+e- linear colliders.

Higgs Boson Production

We studied single Higgs boson production in γγ collisions proceeding via the hadronic content of the photon. For SM Higgs masses of current theoretical interest, the resolved photon contributions are non-negligible in precision cross section measurements. We found that production of the heavier Higgs bosons H0 and A0 of the MSSM can probe regions of the SUSY parameter space that will complement other measurements. Finally, we showed that associated tH± production in γγ collisions can be used to make an accurate determination of tan β for low and high tan β by precision measurements of the γγ → H±t + X cross section.

Event Rates

The production of two standard model Higgs bosons via the WW fusion process e+e− →[Formula: see text] would test the predicted HHH, HWW and HHWW couplings. At TeV energies this fusion cross section dominates over that from e+e− →ZHH and would give significant event rates for mH ≲ 1/2 MZ at high luminosity e+e− colliders. We evaluate the rates and present the dynamical distributions.

Associated Production

The production of a Standard Model Higgs boson in association with a top quark pair at the upcoming high luminosity run (15 fb -1 integreted luminosity) of the Fermilab Tevatron [Formula: see text] is revisited. For Higgs masses below 140 GeV we demonstrate that the production cross section times branching ratio for [Formula: see text] decays yields a significant number of events and that this mode is competitive with and complementary to the searches using [Formula: see text], ZH associated production. For higher mass Higgs bosons the H → W+ W- decays are more difficult but have the potential to provide a few spectacular events.

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.
