Inelastic dark matter from dark Higgs boson decays at FASER

open access: yesJournal of High Energy Physics, 2022
We consider inelastic dark matter scenarios with dark photon mediator and a dark Higgs boson. The dark Higgs boson spontaneously breaks the gauge symmetry associated with the dark photon, and gives the mass to the dark photon and the mass difference to ...

The Interplay Between Collider Searches For Supersymmetric Higgs Bosons and Direct Dark Matter Experiments [PDF]

open access: yes, 2006
In this article, we explore the interplay between searches for supersymmetric particles and Higgs bosons at hadron colliders (the Tevatron and the LHC) and direct dark matter searches (such as CDMS, ZEPLIN, XENON, EDELWEISS, CRESST, WARP and others).

Machine-Learning Analysis of Radiative Decays to Dark Matter at the LHC

open access: yesJournal of High Energy Physics
The search for weakly interacting matter particles (WIMPs) is one of the main objectives of the High Luminosity Large Hadron Collider (HL-LHC). In this work we use Machine-Learning (ML) techniques to explore WIMP radiative decays into a Dark Matter (DM ...

Optimizing pixel tracklet searches for shorter lifetimes

open access: yesJournal of High Energy Physics, 2023
Pixel tracklets, disappearing tracks reconstructed with only pixel hits, have proven to be a promising technique in LHC analyses to search for dark matter candidates at the LHC that belong to a nearly-degenerate electroweak multiplet.

Technicolor Dark Matter [PDF]

open access: yes, 2008
Dark Matter candidates are natural in Technicolor theories. We introduce a general framework allowing to predict signals of Technicolor Dark Matter at colliders and set constraints from earth based experiments such as CDMS and XENON.

Singlet-doublet fermionic dark matter in gauge theory of baryons

open access: yesJournal of High Energy Physics
We are considering a minimal U(1) B extension of the Standard Model (SM) by promoting the baryon number as a local gauge symmetry to accommodate a stable dark matter (DM) candidate. The gauge theory of baryons induces non-trivial triangle gauge anomalies,

Vector portals at future lepton colliders

open access: yesJournal 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 freeze-in with a heavy mediator: beyond the EFT approach

open access: yesJournal of High Energy Physics, 2022
We study dark matter freeze-in scenarios where the mass of the mediator particle that couples dark matter to the Standard Model is larger than the reheat temperature, T RH , in the early Universe.

Changes in Dark Matter Properties After Freeze-Out

open access: yes, 2008
The properties of the dark matter that determine its thermal relic abundance can be very different from the dark matter properties today. We investigate this possibility by coupling a dark matter sector to a scalar that undergoes a phase transition after

Dark matter in multi-singlet extensions of the Standard Model

open access: yesJournal 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.
