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.

Spin-independent DM–nucleon cross section versus DM mass. The upper band (3) corresponds to fermion DM, the middle one (2) to vector DM and the lower one (1) to scalar DM. The solid, dashed and dotted lines represent XENON100 (2012 data [1105]), XENON100 upgrade and XENON1T sensitivities, respectively

Fig154: Spin-independent DM–nucleon cross section versus DM mass. The upper band (3) corresponds to fermion DM, the middle one (2) to vector DM and the lower one (1) to scalar DM. The solid, dashed and dotted lines represent XENON100 (2012 data [1105]), XENON100 upgrade and XENON1T sensitivities, respectively

Mentions: In these models, the Higgs is responsible for both DM annihilation and elastic scattering of DM with nuclei. Thus, cosmological measurements made by the WMAP and PLANCK satellites [46, 47] basically determine the couplings of the Higgs to DM and thus the spin-independent DM–nucleon cross section for a given DM mass. The same coupling will also determine the Higgs partial decay widths into invisible DM particles if . The discovery of a Higgs boson with a mass GeV with a small invisible decay branching ratio is incompatible with DM with GeV. This applies in particular to the case of scalar DM with a mass of 5–10 GeV considered, for instance, in Ref. [1407]. Figure 154 displays the predictions for the spin-independent DM–nucleon cross section after imposing the WMAP and 10 % constraints (allowing the invisible width to be 20% does not change the result significantly). The upper band corresponds to the fermion Higgs-portal DM and is excluded by XENON100, while scalar and vector DM are both allowed for a wide range of masses. The typical value for the scalar is a few times pb, whereas for vectors is larger by a factor of 3, which accounts for the number of degrees of freedom. We note that a large fraction of the parameter space will be probed by XENON1T except for a small region where and the Higgs–DM coupling is extremely small.
