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 ...

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 ...

Maverick dark matter at colliders [PDF]

open access: yes, 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 ...

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 ...

Electroweak Multiplet Dark Matter at Future Lepton Colliders [PDF]

open access: yes, 2018
An 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 triplets,

Search for an invisible scalar in t t ¯ $$ t\overline{t} $$ final states at the LHC

open access: yesJournal 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

open access: yesJournal 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 ...

A new LHC search for dark matter produced via heavy Higgs bosons using simplified models

open access: yesJournal 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.

Forecasting dark showers at Belle II

open access: yesJournal of High Energy Physics, 2022
Dark showers from strongly interacting dark sectors that confine at the GeV scale can give rise to novel signatures at e + e − colliders. In this work, we study the sensitivity of B factory experiments to dark showers produced through an effective ...

Fake Dark Matter at Colliders

open access: yes, 2009
If the dark matter (DM) consists of a weakly interacting massive particle (WIMP), it can be produced and studied at future collider experiments like those at the LHC. The production of collider-stable WIMPs is characterized by hard scattering events with
