Dark vector mesons at LHC forward detector searches
Journal of High Energy Physics, 2023 Confining gauge dynamics in a dark sector is promising to provide dark matter with a mass in the range of sub-GeV to GeV. Such dark sectors consist of composite particles such as dark baryons and dark mesons, that are neutral under the standard-model ...

Searching for inelastic dark matter with future LHC experiments
Journal of High Energy Physics, 2022 We consider a dark sector containing a pair of almost degenerate states coupled to the Standard Model through a dark photon mediator. This set-up constitutes a simple realization of the inelastic dark matter scenario.

Electroweak dark matter at future hadron colliders [PDF]
Physical Review D, 2018 In a large class of scenarios, dark matter (DM) particles that belong to a multiplet of the standard model (SM) weak interactions are challenging to probe in direct detection experiments due to loop-suppressed cross-sections.

Distinguishing two dark matter component particles at e + e − colliders
Journal of High Energy Physics, 2022 We investigate ways of identifying two kinds of dark matter (DM) component particles at high-energy colliders. The strategy is to notice and distinguish double-peaks(humps) in the missing energy/transverse energy distribution.

Dark Matter Searches at Colliders [PDF]
Annual Review of Nuclear and Particle Science, 2018 Colliders, among the most successful tools of particle physics, have revealed much about matter. This review describes how colliders contribute to the search for particle dark matter, focusing on the highest-energy collider currently in operation, the ...

Maverick dark matter at colliders [PDF]
, 2010 Assuming that dark matter is a weakly interacting massive particle (WIMP) species X produced in the early Universe as a cold thermal relic, we study the collider signal of pp or $ p\bar{p} \rightarrow \bar{X}X $ + jets and its distinguishability from ...

Electroweak multiplet dark matter at future lepton colliders [PDF]
Journal of High Energy Physics, 2018 A bstractAn electroweak multiplet stable due to a new global symmetry is a simple and well-motivated candidate for thermal dark matter. We study how direct searches at a future linear collider, such as the proposed CLIC, can constrain scalar and fermion ...

Dark matter at colliders: A Model independent approach [PDF]
, 2004 Assuming that cosmological dark matter consists of weakly interacting massive particles, we use the recent precise measurement of cosmological parameters to predict the guaranteed rates of production of such particles in association with photons at ...

Unraveling the Scotogenic model at muon collider
Journal of High Energy Physics, 2022 The Scotogenic model extends the standard model with three singlet fermion N i and one inert doublet scalar η to address the common origin of tiny neutrino mass and dark matter. For fermion dark matter N 1, a hierarchical Yukawa structure ∣ y 1 e ∣ ≪ ∣ y
