Dark sector glueballs at the LHC

Journal of High Energy Physics
We study confining dark sectors where the lightest hadrons are glueballs. Such models can provide viable dark matter candidates and appear in some neutral naturalness scenarios.

SUSY Tools for Dark Matter and at the Colliders

, 2010
With present and upcoming SUSY searches both directly, indirectly and at accelerators, the need for accurate calculations is large. We will here go through some of the tools available both from a dark matter point of view and at accelerators. For natural

Constraining Asymmetric Dark Matter using colliders and direct detection

Journal of High Energy Physics
We reappraise the viability of asymmetric dark matter (ADM) realized as a Dirac fermion coupling dominantly to the Standard Model fermions. Treating the interactions of such a DM particle with quarks/leptons in an effective-interactions framework, we ...

Vector dark matter from the 5-dimensional representation of SU(2) L

Journal of High Energy Physics
The introduction of electroweak multiplets that transform under any representation of the standard SU(2) L gauge group suggests the existence of electrically neutral stable particles capable of serving as cold dark matter in the ΛCDM cosmological model ...

Novel collider signatures in the type-I 2HDM+a model

Journal of High Energy Physics
The 2HDM+a model is one of the main models used in the interpretations of dark matter searches at the LHC. So far, all the 2HDM+a benchmarks considered by the ATLAS and CMS experiments are limited to a type-II Yukawa sector, in which the Higgs bosons A ...

ILC Cosmology

, 2005
Recent breakthroughs in cosmology pose questions that require particle physics answers. I review the problems of dark matter, baryogenesis, and dark energy and discuss how particle colliders, particularly the International Linear Collider, may advance ...

WIMP Dark Matter at the International Linear Collider

, 2019
In this study, the sensitivity of future lepton colliders to WIMP dark matter is evaluated assuming WIMP pair production accompanied by a photon from initial state radiation, through which the process can be identified. A full detector simulation for the International Large Detector (ILD) concept at the International Linear Collider (ILC) is performed ...

Dark fluxes from electromagnetic cascades

Journal of High Energy Physics
We study dark sector production in electromagnetic (EM) cascades. This problem requires accurate simulations of Standard Model (SM) and dark sector processes, both of which impact angular and energy distributions of emitted particles that ultimately ...

Unveiling desert region in inert doublet model assisted by Peccei-Quinn symmetry

Journal of High Energy Physics
The Inert Higgs Doublet model (IDM), assisted by Peccei-Quinn (PQ) symmetry, offers a simple but natural framework of a dark sector that accommodates Weakly Interacting Massive Particle (WIMP) and axion as dark matter components.
