Vector Boson Fusion topology and simplified models for dark matter searches at colliders
Journal of High Energy Physics, 2023 In this paper, we study the possible searches at colliders using Vector Boson Fusion topology in the context of Simplified Models signatures. We examine the possible physics reach of these searches with regard to monojet-type searches, and determine how ...

Dark matter signals in dilepton production at hadron colliders
Physical Review D, 2015 We show that new physics can show up in dileptonic events through its radiative contributions to the dilepton invariant mass, leading to unique "monocline" features in $m_{\ell\ell}$, as well as the angular distribution of the leptons. We focus in particular on the case of dark matter with scalar messengers coupling it to the quarks and leptons ...

Baryogenesis and Dark Matter from $B$ Mesons
, 2019 We present a new mechanism of Baryogenesis and dark matter production in which both the dark matter relic abundance and the baryon asymmetry arise from neutral $B$ meson oscillations and subsequent decays. This set-up is testable at hadron colliders and $

Journal of High Energy PhysicsWe present a new way to interpret Top Standard Model measurements going beyond the SMEFT framework. Instead of the usual paradigm in Top EFT, where the main effects come from tails in momenta distributions, we propose an interpretation in terms of new ...

Neutralino Dark Matter in 2005
, 2005 I summarize some recent work on supersymmetric neutralinos as candidates for cold Dark Matter in the Universe. This includes a new scan of mSUGRA parameter space, with special emphasis on neutralinos annihilating predominantly through exchange of the ...

Pseudo-Nambu-Goldstone-boson dark matter from three complex scalars
Journal of High Energy PhysicsThis study explores a dark matter model in which a pseudo-Nambu-Goldstone boson arises as a viable dark matter candidate from the spontaneous and soft breaking of global U(1) symmetries and stabilized by a residual ℤ 3 discrete symmetry.

The pursuit of dark matter at colliders—an overview [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2018 Dark matter is one of the main puzzles in fundamental physics and the goal of a diverse, multi-pronged research program. Underground and astrophysical searches search for dark matter particles in the cosmos, either by interacting directly or by searching for dark matter annihilation.

Complex dark photon dark matter EFT
Journal of High Energy PhysicsWe construct an effective field theory for complex Stueckelberg dark photon dark matter. Such an effective construction can be realized by writing down a complete set of operators up to dimension six built with the complex dark photon and Standard Model ...

, 2012 We show a TeV-scale seesaw model where Majorana neutrino masses, the dark matter mass, and stability of the dark matter can be all originated from the U(1)_{B-L} gauge symmetry. Dirac mass terms for neutrinos are forbidden at the tree level by U(1)_{B-L},
