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 ...

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 Abstract Dark matter is one of the main puzzles in fundamental physics and the goal of a diverse, multi-pronged research programme. Underground and astrophysical searches look 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.

Collider Signatures of Sneutrino Cold Dark Matter [PDF]
Physics Letters B, 2000 Decays of sneutrinos are considered in the case that in the presence of lepton-number violation in the sneutrino sector the lighter tau-sneutrino is the Lightest Supersymmetric Particle and the Cold Dark Matter in the Universe. In such circumstances the signals from sparticle decays differ considerably from the ``standard'' case where the lightest ...

Machine-Learning Analysis of Radiative Decays to Dark Matter at the LHC
Journal of High Energy PhysicsThe search for weakly interacting matter particles (WIMPs) is one of the main objectives of the High Luminosity Large Hadron Collider (HL-LHC). In this work we use Machine-Learning (ML) techniques to explore WIMP radiative decays into a Dark Matter (DM ...

Inelastic dark matter from dark Higgs boson decays at FASER
Journal of High Energy Physics, 2022 We consider inelastic dark matter scenarios with dark photon mediator and a dark Higgs boson. The dark Higgs boson spontaneously breaks the gauge symmetry associated with the dark photon, and gives the mass to the dark photon and the mass difference to ...
