IDM Benchmarks for the LHC and Future Colliders

Abstract

We present cross-section expectations for various processes and collider options, for benchmark scenarios of the Inert Doublet Model, a Two Higgs Doublet Model with a dark matter candidate. The proposed scenarios are consistent with current dark matter constraints, including the most recent bounds from the XENON1T experiment and relic density, as well as with known collider and low-energy limits. These benchmarks, chosen in earlier work for studies at e+e− colliders, exhibit a variety of kinematic features that should be explored at current and future runs of the LHC. We provide cross sections for all relevant production processes at 13 TeV, 27 TeV and 100 TeV proton collider, as well as for a possible 10 TeV and 30 TeV muon collider.

Models with (broken) Z2 symmetries

“…Two parameters (𝑚 ℎ and 𝑣) are fixed by current measurements. The model is subject to a large number of experimental and theoretical constraints [1][2][3][4]10]. A general feature is a relatively strong degeneracy between the additional masses of the second doublet, as well as a minimal mass scale for the dark matter candidate resulting from a combination of relic density and signal strength measurement constraints (see [1,4] for a detailed discussion).…”

“…In [4], a sensitivity comparison for selected benchmark points [3,4,11] using a simple counting criteria was used, where a benchmark point is considered reachable if at least 1000 signal events are produced using nominal luminosity of the respective collider (c.f. also [12]).…”

“…also [12]). The results are presented in table 1, with the accompagnying figures, displaying production cross sections Taken from [4]. The lines correspond to the cross-sections required to prodce at least 1000 events using the respective design luminosity.…”

“…Bottom right Same for 𝜇 + 𝜇 − colliders. Taken from[4]. The lines correspond to the cross-sections required to prodce at least 1000 events using the respective design luminosity.…”

Higher Order Radiative Corrections in QCD

“…• WG2: "Precision Phenomenology" to provide precise theoretical predictions for LHC in the high-energy run to push the frontiers regarding precision and sensitivity; to compute cross sections for Higgs boson production (single and multiple Higgs boson production), EW gauge bosons, heavy-quark, multi-jet, and ultra-rare processes in differential kinematics [5][6][7]. • WG3: "Future Colliders" to assess the discovery potential of future high energy colliders based on the experimental results from the high-energy run of the LHC combined with progress in theoretical research [8,9]. • WG4: "Networking and Training" for efficient coordination of the Action activities, transparent administration, and reliable reporting.…”
