Secluded dark matter in gauged B − L model
Journal of High Energy Physics, 2022 We consider the gauged B − L model which is extended with a secluded dark sector, comprising of two dark sector particles. In this framework the lightest Z $$ \mathcal{Z} $$ 2-odd particle is the dark matter candidate, having a feeble interaction with ...

Supersymmetry and the collider dark matter picture [PDF]
Modern Physics Letters A, 2019 One of the key questions in particle physics and astrophysics is the nature of dark matter, the existence of which has been confirmed in many astrophysical and cosmological observations. Besides direct and indirect detection experiments, collider searches for dark matter offer the unique possibility to not only detect dark matter particles but in the ...

Search for an invisible scalar in t t ¯ $$ t\overline{t} $$ final states at the LHC
Journal of High Energy Physics, 2023 We use the current t t ¯ $$ t\overline{t} $$ experimental analysis to look for Dark Matter (DM) particles hidden in the final state. We present a phenomenological study where we successfully perform the reconstruction of a t t ¯ $$ t\overline{t ...

A Dark-Matter Search Using the Final CDMS II Dataset and a Novel Detector of Surface Radiocontamination [PDF]
, 2012 Substantial evidence from galaxies, galaxy clusters, and cosmological scales suggests that ~85% of the matter of our universe is invisible. The missing matter, or "dark matter" is likely composed of non-relativistic, non-baryonic particles, which have ...

Search for axion(-like) particles in heavy-ion collisions
Journal of High Energy Physics, 2022 We propose a novel way to search for axion(-like) particles in heavy-ion collisions using prompt photons as the probe and the property of conversion between photon and axion(-like) particles under a strong magnetic field generated in the non-central ...

The pursuit of dark matter at colliders—an overview [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2018 Dark matter is one of the main puzzles in fundamental physics and the goal of a diverse, multi-pronged research program. Underground and astrophysical searches search for dark matter particles in the cosmos, either by interacting directly or by searching for dark matter annihilation.

A new LHC search for dark matter produced via heavy Higgs bosons using simplified models
Journal of High Energy Physics, 2023 Searches for dark matter produced via scalar resonances in final states consisting of Standard Model (SM) particles and missing transverse momentum are of high relevance at the LHC.

Maverick dark matter at colliders [PDF]
Journal of High Energy Physics, 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 ppbar -> XXbar + jets and its distinguishability from standard-model background processes associated with jets and missing energy.

Dark Matter Phenomenology at Colliders [PDF]
, 2020 Dark Matter candidates are required in physics beyond the Standard Model. The preferable models should not only explain the observed phenomena, but also be testable by experiments including direct detection, indirect detection, and collider searches.
