Vector Boson Fusion topology and simplified models for dark matter searches at colliders [PDF]
Journal of High Energy Physics, 2023 In this paper, we study the possible searches at colliders using Vector Boson Fusion topology in the context of Simplified Models signatures. We examine the possible physics reach of these searches with regard to monojet-type searches, and determine how ...

Constraining Asymmetric Dark Matter using colliders and direct detection [PDF]
Journal of High Energy PhysicsWe 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 ...

Experimental implications for a linear collider of SUSY dark matter scenario [PDF]
, 2004 This talk presents the detection issues for the lightest slepton \tilde{\tau}_1 at a future e+e- TeV collider given the dark matter constraints set on the SUSY mass spectrum by the WMAP results.

Multicomponent dark matter with collider implications [PDF]
Journal of High Energy PhysicsThe present work aims to study an extension of the Standard Model (SM) that addresses the prominent SM shortcomings, i.e., can explain the neutrino mass, the dark matter (DM) content, and the matter-antimatter asymmetry of the Universe.

Journal of High Energy Physics, 2023 We explore a possible signal of the presence of relatively light electroweakinos (ewinos) and a singlet-like scalar (a S ) of the Z 3-symmetric Next-to-Minimal Supersymmetric Standard Model (Z 3-NMSSM) in the cascade decays of not so heavy top squarks ...

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.

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.

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

Lighting up the LHC with Dark Matter
Journal of High Energy Physics, 2023 We show that simultaneously explaining dark matter and the observed value of the muon’s magnetic dipole moment may lead to yet unexplored photon signals at the LHC.
