“…58). The pair production processes e + e − → H + H − and e + e − → HA will give access to these heavy Higgs bosons almost up to the kinematic limit [202,203]. Two separate scenarios have recently been studied [9], with a mass of the pseudoscalar Higgs boson A of m A =902 GeV (Model I) or m A =742 GeV (Model II).…”

A comprehensive review of physics at an e + e − Linear Collider in the energy range of √ s = 92 GeV-3 TeV is presented in view of recent and expected LHC results, experiments from low energy as well as astroparticle physics. The report focuses in particular on Higgs boson, top quark and electroweak precision physics, but also discusses several models of beyond the Standard Model physics such as Supersymmetry, little Higgs models and extra gauge bosons. The connection to cosmology has been analyzed as well.

A comprehensive review of physics at an linear collider in the energy range of GeV–3 TeV is presented in view of recent and expected LHC results, experiments from low-energy as well as astroparticle physics. The report focusses in particular on Higgs-boson, top-quark and electroweak precision physics, but also discusses several models of beyond the standard model physics such as supersymmetry, little Higgs models and extra gauge bosons. The connection to cosmology has been analysed as well.

“…In fact, the relation between its mass, M A , and that of the lightest neutralino, M χ 0 1 , determines the cross section of the χ 0 1 χ 0 1 → A 0 annihilation process in the early universe, which could have been responsible for determining the amount of relic dark matter we observe in the universe today [2]. Pair production of heavy neutral Higgs bosons at the linear collider has already been studied for several scenarios with lighter particles [3,4]. This analysis is interesting for assessing the detector requirements in terms of b-tagging efficiency, since the signal has four b jets and small production cross section, jet clustering, di-jet invariant mass reconstruction and detector time stamping capabilities in presence of two-photon machine-induced background.…”

The precise determination of the masses of the CP-odd and -even heavy Higgs bosons is an important part of the study of Supersymmetry and its relation with cosmology through dark matter. This note presents a determination of the A 0 mass with the e + e − → H 0 A 0 → b bb b process for a dark matter motivated cMSSM scenario with M A = 1141 GeV at CLIC. The analysis is performed with full simulation and reconstruction at √ s=3 TeV accounting for beamstrahlung effects. SM and SUSY backgrounds are considered and the effect of the overlay of γγ → hadrons events on the signal is studied for various assumptions for the detector time-stamping capabilities. The di-jet mass resolution is improved by applying a kinematic fit. The A 0 mass can be determined with a statistical accuracy of ≃ 3-5 GeV for 3 ab −1 of statistics and 0 to 20 bunch crossings of γγ background integrated in one event, respectively.
