Multicomponent dark matter with collider implications

Journal of High Energy Physics
The 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.

Dark Matter at the International Linear Collider

, 2018
The International Linear Collider (ILC) is a planned electron-positron colliderwith polarised beams and centre-of-mass energies of up to 500 GeV. By performinghigh-precision measurements of Standard Model observables and searches for newparticles it can complement the potential of the Large Hadron Collider (LHC).One of the most prominent open questions

Fermion-portal dark matter at a high-energy muon collider

Physical Review D
In this work, we provide a comprehensive study of fermion-portal dark matter models in the freeze-in regime at a future muon collider. For different possible nonsinglet fermion portals, we calculate the upper bound on the mediator’s mass arising from the relic abundance calculation and discuss the reach of a future muon collider in probing their viable

Probing Inert Triplet Model at a multi-TeV muon collider via vector boson fusion with forward muon tagging

Journal of High Energy Physics
This study investigates the potential of a multi-TeV Muon Collider (MuC) for probing the Inert Triplet Model (ITM), which introduces a triplet scalar field with hypercharge Y = 0 to the Standard Model.

Gravity-Mediated Dark Matter at a low reheating temperature

Journal of High Energy Physics
We present a new study on the Gravity-Mediated Dark Matter (GMDM) scenario, where interactions between dark matter (DM) and the Standard Model are mediated by spin-two particles.

Experimental implications for a linear collider of SUSY dark matter scenario

, 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.

Discovering Electroweak Interacting Dark Matter at Muon Colliders Using Soft Tracks

Physical Review Letters
Minimal dark matter models feature one neutral particle that serves as a thermal relic dark matter candidate, as well as quasidegenerate charged states with TeV masses. When the charged states are produced at colliders, they can decay into dark matter and a low-momentum (soft) charged particle, which is challenging to reconstruct at hadron colliders ...

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.
