Heavy Higgs boson production at colliders in the singlet-triplet scotogenic dark matter model [PDF]
, 2016 A bstractWe consider the possibility that the dark matter particle is a scalar WIMP messenger associated to neutrino mass generation, made stable by the same symmetry responsible for the radiative origin of neutrino mass.

Inelastic Dirac dark matter [PDF]
Journal of High Energy Physics, 2022 Feebly interacting thermal relics are promising dark matter candidates. Among them, scenarios of inelastic Dark Matter evade direct detection by suppressed elastic scattering off atomic nuclei.

Freeze-In dark matter with displaced signatures at colliders [PDF]
, 2015 Dark matter, X, may be generated by new physics at the TeV scale during an early matter-dominated (MD) era that ends at temperature TR ≪ TeV. Compared to the conventional radiation-dominated (RD) results, yields from both Freeze-Out and Freeze-In ...

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 ...

Forecasting dark showers at Belle II
Journal 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 ...

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 ...

Searches for vector-like quarks at future colliders and implications for composite Higgs models with dark matter [PDF]
Journal of High Energy Physics, 2018 Many composite Higgs models predict the existence of vector-like quarks with masses outside the reach of the LHC, e.g. mQ ≳ 2 TeV, in particular if these models contain a dark matter candidate.

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 ...

Characterising dark matter searches at colliders and direct detection experiments: vector mediators [PDF]
, 2014 A bstractWe introduce a Minimal Simplified Dark Matter (MSDM) framework to quantitatively characterise dark matter (DM) searches at the LHC. We study two MSDM models where the DM is a Dirac fermion which interacts with a vector and axial-vector mediator.

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.
