Closing up on Dark Sectors at Colliders: from 14 to 100 TeV / Harris, Philip (CERN) ; Khoze, Valentin V. (Durham U., IPPP) ; Spannowsky, Michael (Durham U., IPPP) ; Williams, Ciaran (SUNY, Buffalo)
We investigate the reach of the LHC Run 2 and that of a future circular hadron collider with up to 100 TeV centre of mass energy for the exploration of potential Dark Matter sectors. These dark sectors are conveniently and broadly described by simplified models. [...]

Constraining Dark Sectors at Colliders: Beyond the Effective Theory Approach / Harris, Philip (CERN) ; Khoze, Valentin V. (Durham U., IPPP ; Durham U.) ; Spannowsky, Michael (Durham U., IPPP ; Durham U.) ; Williams, Ciaran (Bohr Inst. ; SUNY, Buffalo)
We outline and investigate a set of benchmark simplified models with the aim of providing a minimal simple framework for an interpretation of the existing and forthcoming searches of dark matter particles at the LHC. The simplified models we consider provide microscopic QFT descriptions of interactions between the Standard Model partons and the dark sector particles mediated by the four basic types of messenger fields: scalar, pseudo-scalar, vector or axial-vector. [...]

Dark matter as the trigger of flavor changing neutral current decays of the top quark / Jueid, Adil (IBS, Daejeon) ; Kanemura, Shinya (Osaka U.)
We suggest a simplified model that simultaneously addresses the dark-matter problem and give rise to top quark flavor changing neutral current (FCNC) interactions at the one-loop order. The model consists of two extra $SU(2)_L$ gauge singlets: a colored mediator of spin zero ($S$) and a right-handed fermion ($\chi$) both are odd under an ad-hoc $Z_2$ symmetry. [...]

VBS ${\rm W}^\pm {\rm W}^\pm {\rm H}$ production at the HL-LHC and a 100 TeV $pp$-collider / Englert, Christoph (SUPA, UK ; Glasgow U.) ; Li, Qiang (Peking U. ; Peking U., SKLNPT ; CAS, CEPP, Beijing) ; Spannowsky, Michael (Durham U., IPPP) ; Wang, Mengmeng (Peking U., SKLNPT ; Peking U.) ; Wang, Lei (Peking U., SKLNPT ; Peking U.)
${\rm W}^\pm {\rm W}^\pm {\rm H}$ production at hadron colliders through vector boson scattering is a so far unconsidered process, which leads to a clean signature of two same-sign charged leptons and two widely separated jets. This process is sensitive to the ${\rm HHH}$ and ${\rm WWHH}$ couplings and any deviation of these couplings from their SM predictions serves as direct evidence of new physics beyond the SM. [...]

Dark matter in theories of gauge-mediated supersymmetry breaking / Dimopoulos, S. (CERN ; Stanford U., Phys. Dept.) ; Giudice, G.F. (CERN) ; Pomarol, A. (CERN)
In gauge-mediated theories supersymmetry breaking originates in a strongly interacting sector and is communicated to the ordinary sparticles via SU(3)$\times$SU(2)$\times$U(1) carrying ``messenger'' particles. Stable baryons of the strongly interacting supersymmetry breaking sector naturally weigh $\sim$ 100 TeV and are viable cold dark matter candidates. [...]

S-Channel Dark Matter Simplified Models and Unitarity / Englert, Christoph (Glasgow U. ; SUPA, UK) ; McCullough, Matthew (CERN) ; Spannowsky, Michael (Durham U., IPPP ; Durham U.)
The ultraviolet structure of $s$-channel mediator dark matter simplified models at hadron colliders is considered. In terms of commonly studied $s$-channel mediator simplified models it is argued that at arbitrarily high energies the perturbative description of dark matter production in high energy scattering at hadron colliders will break down in a number of cases. [...]

Constraints on spin-0 dark matter mediators and invisible Higgs decays using ATLAS 13 TeV pp collision data with two top quarks and missing energy in the final state
This paper presents a statistical combination of searches targeting final states with two top quarks and invisible particles and characterised by the presence of zero, one or two leptons, at least one jet originating from a $b$-quark and missing transverse momentum. [...]

Search for a light Dark Matter mediator in the dijet mass spectrum from pp collisions at √s = 13 TeV with the ATLAS / Krizka, Karol (University of Chicago, Enrico Fermi Institute) /ATLAS Collaboration
The ATLAS experiment has a rich program of searches for Dark Matter candidates. Most of them use a simplified model, where the colliding partons produce a mediator particle that decays into Dark Matter. [...]
