Maverick dark matter at colliders [PDF]

open access: yesJournal 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 ...

Distinguishing two dark matter component particles at e + e − colliders

open access: yesJournal 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.

Hunting ewinos and a light scalar of Z 3-NMSSM with a bino-like dark matter in top squark decays at the LHC

open access: yesJournal 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

open access: yesJournal 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

open access: yesJournal 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.

Unraveling the Scotogenic model at muon collider

open access: yesJournal 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

open access: yesJournal 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.

Associated production of neutrino and dark fermion at future lepton colliders

open access: yesJournal of High Energy Physics, 2023
Fermionic dark matter can be pairly produced and hence searched with missing energy at colliders. We extend such probe to the associated production of a neutrino and a dark sector fermion at the future e + e − colliders such as CEPC, FCC-ee, ILC, and ...

Secluded dark matter in gauged B − L model

open access: yesJournal 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 ...

Multilepton signatures from dark matter at the LHC

open access: yesJournal of High Energy Physics, 2022
Leptonic signatures of Dark Matter (DM) are one of the cleanest ways to discover such a secluded form of matter at high energy colliders. We explore the full parameter space relevant to multi-lepton (2- and 3-lepton) signatures at the Large Hadron ...
