Searches for dark matter at colliders typically involve signatures with energetic initial-state radiation without visible recoil particles. Searches for mono-jet or mono-photon signatures have yielded powerful constraints on dark matter interactions with Standard Model particles. I extend this to the mono-Z, W, and Higgs signatures and reinterpret ATLAS analyses of events with missing...

Motivated by the recent discovery of the Higgs boson, we investigate the possibility that a missing energy plus Higgs final state is the dominant signal channel for dark matter at the LHC. We consider examples of higher-dimension operators where a Higgs and dark matter pair are produced through an off-shell Z or photon, finding potential sensitivity at the LHC to cutoff scales of around a few...

The production cross section of dark matter at the LHC is constrained to be in order of picobarn assuming a minimal, SM singlet dark matter. However the dark sector generically can be non minimal that it might have new dark gauge interactions. The dark gauge boson can decay to SM particles via kinetic mixing. In this scenario, the dark gauge boson is produced at the LHC in association with the...

This talk discusses the collider phenomenolgy of a nonthermal dark
matter model with a 1-GeV dark matter candidate. Together with
additional colored states, the dark matter also explains baryongensis.
Since the light dark matter is not parity-protected, it can be singly
produced at the LHC. This leads to large missing energy associated with
an energetic jet whose transverse momentum...

We perform a detailed study of the dark Z' portal using a generic parametrization of the Z'-quarks couplings. We present a comprehensive study of the collider phenomenology and Dark Matter observables. We highlight the importance of complementary searches for dark matter, and outline the excluded versus still viable parameter space regions of the dark Z' portal.
