Dark fluxes from electromagnetic cascades

Journal of High Energy Physics
We study dark sector production in electromagnetic (EM) cascades. This problem requires accurate simulations of Standard Model (SM) and dark sector processes, both of which impact angular and energy distributions of emitted particles that ultimately ...

Unveiling desert region in inert doublet model assisted by Peccei-Quinn symmetry

Journal of High Energy Physics
The Inert Higgs Doublet model (IDM), assisted by Peccei-Quinn (PQ) symmetry, offers a simple but natural framework of a dark sector that accommodates Weakly Interacting Massive Particle (WIMP) and axion as dark matter components.

Hadronic mono-W′ probes of dark matter at colliders

Journal of High Energy Physics
Particle collisions at the energy frontier can probe the nature of invisible dark matter via production in association with recoiling visible objects. We propose a new potential production mode, in which dark matter is produced by the decay of a heavy ...

The Muonic Portal to Vector Dark Matter: connecting precision muon physics, cosmology, and colliders

Journal of High Energy Physics
We present a comprehensive study of the Muonic Portal to Vector Dark Matter (MPVDM), a minimal extension of the Standard Model featuring a new SU (2) D gauge symmetry and vector-like muons that mediate interactions between the dark sector and the muon ...

Dark particles at the LHC: LHC-friendly dark matter characterization via non-linear EFT

Journal of High Energy Physics
In this work we illustrate a general framework to describe the LHC phenomenology of extended scalar (and fermion) sectors, with focus on dark matter (DM) physics, based on an effective field theory (EFT) with non-linearly realized electroweak symmetry ...

Dark Matter physics in general NMSSM

Journal of High Energy Physics
In the General Next-to-Minimal Supersymmetric Standard Model (GNMSSM), singlet particles may form a secluded sector of dark matter (DM), in which Singlino-like DM could achieve the observed relic abundance through various channels such as χ ~ 1 0 χ ~ 1 0

Collider signatures of near-continuum dark matter

Journal of High Energy Physics
Abstract In this paper we study a near-continuum dark matter model, in which dark sector consists of a tower of closely spaced states with weak-scale masses. We construct a five-dimensional model which naturally realizes this spectrum.

Dark matter with exotic mediators: the diquark portal

Journal of High Energy Physics
In this work we build out complete mediator sectors for models of frustrated dark matter (fDM), a new paradigm in which fermionic dark matter couples to the Standard Model (SM) through a scalar-fermionic mediator pair.
