Journal of High Energy PhysicsDark matter may form bound states in a dark sector with an attractive force between two dark matter particles. Searches for dark matter at colliders can differ dramatically from routine searches if bound states, dubbed darkonia, are produced and decay ...

Collider signatures of the gauge-Higgs dark matter [PDF]
Physical Review D, 2010 A recently proposed SO(5)xU(1) gauge-Higgs unification model in the Randall-Sundrum warped space contains a very interesting dark matter candidate, the Higgs boson. As a part of the fifth component of a five-dimensional gauge field, the four-dimensional neutral Higgs boson has odd H parity while all the other standard model particles have even parity ...

Dark matter freeze-in with a heavy mediator: beyond the EFT approach
Journal of High Energy Physics, 2022 We study dark matter freeze-in scenarios where the mass of the mediator particle that couples dark matter to the Standard Model is larger than the reheat temperature, T RH , in the early Universe.

Search for WIMPs at future μ + μ + colliders
Journal of High Energy PhysicsWeakly interacting massive particles (WIMPs) with electroweak charges, such as the wino and the Higgsino, stand out as natural candidates for dark matter in the universe. In this paper, we study the search for WIMPs at future multi-TeV μ + μ + colliders.

Higgs portal dark matter freeze-in at stronger coupling: observational benchmarks
Journal of High Energy PhysicsWe study freeze-in production of Higgs portal dark matter (DM) at temperatures far below the dark matter mass. The temperature of the Standard Model (SM) thermal bath may have never been high such that dark matter production via thermal emission has been

Non-minimal dark matter search in dark matter colliders [PDF]
EPJ Web of Conferences, 2018 In the scenarios of dark matter (DM) with a non-minimal dark sector, we revisit a new detection strategy of observing two or three simultaneous signals from inelastic scattering of a boosted DM [1]. The relativistically incoming DM can scatter off inelastically to a heavier unstable dark sector particle which decays back in to the DM associated with ...

Dark matter search at colliders and neutrino floor *
Chinese Physics C, 2020 Abstract The sensitivity of the direct detection of dark matter (DM) approaches the so-called neutrino floor, below which it is difficult to disentangle the DM candidate from the neutrino background. In this work, we consider the scenario that no DM signals are reported in various DM direct detection experiments and explore whether ...

Displaced Dark Matter at Colliders
, 2009 Models in which the dark matter is very weakly coupled to the observable sector may explain the observed dark matter density, either as a "superWIMP" or as "asymmetric dark matter." Both types of models predict displaced vertices at colliders, with a rich variety of possible phenomenology.
