Simplified models for dark matter interacting with quarks [PDF]

Journal of High Energy Physics, 2013
We investigate simplified models in which dark matter particles, taken to be either Dirac or Majorana fermions, couple to quarks via colored mediators. We determine bounds from colliders and direct detection experiments, and show how the interplay of the two leads to a complementary view of this class of dark matter models.

Simplified models for dark matter searches at the LHC [PDF]

Physics of the Dark Universe, 2015
This document outlines a set of simplified models for dark matter and its interactions with Standard Model particles. It is intended to summarize the main characteristics that these simplified models have when applied to dark matter searches at the LHC, and to provide a number of useful expressions for reference.

A natural scotogenic model for neutrino mass & dark matter

Physics Letters B, 2021
In this letter, we propose an extension of the scotogenic model where singlet Majorana particle can be dark matter (DM) without the need of a highly suppressed scalar coupling of the order $O(10^{-10})$. For that, the SM is extended with three singlet Majorana fermions, an inert scalar doublet, and two (a complex and a real) singlet scalars, with a ...

Vector portals at future lepton colliders

Journal of High Energy Physics
We assess the sensitivity of future lepton colliders to weakly coupled vector dark portals (aka “Z ′ bosons”) with masses ranging from tens of GeV to a few TeV. Our analysis focuses on dark photons and L μ – L τ gauge bosons. We consider both visible and

Dark matter in multi-singlet extensions of the Standard Model

Journal of High Energy Physics
We study the simplest extensions of the Standard Model (SM) that provide Dark Matter (DM) candidates, built with the addition of real singlets and new Z 2 $$ {\mathcal{Z}}_2 $$ symmetries.

Revisiting the fermionic dark matter absorption on electron target

Journal of High Energy Physics, 2022
We perform a systematic study of the fermionic DM absorption interactions on electron target in the context of effective field theory. The fermionic DM absorption is not just sensitive to sub-MeV DM with efficient energy release, but also gives a unique ...
