ABSTRACT

A comprehensive review of physics at an [Formula: see text] linear collider in the energy range of [Formula: see text] 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.

Di-jet invariant mass distribution in inclusive 4-jet  missing energy SUSY events produced in  TeV  collisions for 0.5 ab of fully simulated events. The result of the fit to extract the boson content is shown by the continuous line with the individual W, Z and h components represented by the dotted lines (from [1162])

Fig130: Di-jet invariant mass distribution in inclusive 4-jet missing energy SUSY events produced in  TeV collisions for 0.5 ab of fully simulated events. The result of the fit to extract the boson content is shown by the continuous line with the individual W, Z and h components represented by the dotted lines (from [1162])

Mentions: Decays of charginos and neutralinos into bosons, such as and or , are well suited to collider capabilities. The four-jet + missing energy final states can be studied with good accuracy thanks to the small background and the excellent di-jet mass resolution ensuring separation of W from Z or h masses. Production cross sections of pairs of chargino and neutralino with mass of 216 GeV have been studied at 0.5 TeV and the statistical uncertainty on the cross section has been estimated at 0.6 and 2 %, respectively. It is interesting to observe that decays of SUSY particles, in particular neutralinos into the lightest Higgs boson, h, are common and even enhanced in specific models and combinations of MSSM parameters [1159–1162]. This opens up an interesting perspective of studying SUSY processes through the reconstruction of h pairs missing energy in four jet events, where Higgs-boson production is selected from that of other bosons by di-jet mass (see Fig. 130) and also b-tagging. A further possibility is the study of single Higgs boson plus missing E production via with the decay .Fig. 130
