Minimal Dark Matter bound states at future colliders [PDF]
Journal of High Energy Physics, 2021 Abstract The hypothesis that Dark Matter is one electroweak multiplet leads to predictive candidates with multi-TeV masses that can form electroweak bound states. Bound states with the same quantum numbers as electroweak vectors are found to be especially interesting, as they can be produced resonantly with large cross sections at ...

Forecasting dark showers at Belle II
Journal of High Energy Physics, 2022 Dark showers from strongly interacting dark sectors that confine at the GeV scale can give rise to novel signatures at e + e − colliders. In this work, we study the sensitivity of B factory experiments to dark showers produced through an effective ...

Search for an invisible scalar in t t ¯ $$ t\overline{t} $$ final states at the LHC
Journal of High Energy Physics, 2023 We use the current t t ¯ $$ t\overline{t} $$ experimental analysis to look for Dark Matter (DM) particles hidden in the final state. We present a phenomenological study where we successfully perform the reconstruction of a t t ¯ $$ t\overline{t ...

Search for axion(-like) particles in heavy-ion collisions
Journal of High Energy Physics, 2022 We propose a novel way to search for axion(-like) particles in heavy-ion collisions using prompt photons as the probe and the property of conversion between photon and axion(-like) particles under a strong magnetic field generated in the non-central ...

Spectral Decomposition of Missing Transverse Energy at Hadron Colliders [PDF]
, 2017 We propose a spectral decomposition to systematically extract information of dark matter at hadron colliders. The differential cross section of events with missing transverse energy (MET) can be expressed by a linear combination of basis functions.

SHEDDING LIGHT ON DARK MATTER AT COLLIDERS [PDF]
International Journal of Modern Physics A, 2013 Dark matter remains one of the most puzzling mysteries in Fundamental Physics of our times. Experiments at high-energy physics colliders are expected to shed light to its nature and determine its properties. This review focuses on recent searches for dark matter signatures at the Large Hadron Collider, also discussing related prospects in future e+e ...

A new LHC search for dark matter produced via heavy Higgs bosons using simplified models
Journal of High Energy Physics, 2023 Searches for dark matter produced via scalar resonances in final states consisting of Standard Model (SM) particles and missing transverse momentum are of high relevance at the LHC.

Dark matter search at colliders and neutrino floor *
Chinese Physics C, 2020 Abstract The sensitivity of the direct detection of dark matter (DM) approaches the so-called neutrino floor, below which it is difficult to disentangle the DM candidate from the neutrino background. In this work, we consider the scenario that no DM signals are reported in various DM direct detection experiments and explore whether ...

Displaced Dark Matter at Colliders
, 2009 Models in which the dark matter is very weakly coupled to the observable sector may explain the observed dark matter density, either as a "superWIMP" or as "asymmetric dark matter." Both types of models predict displaced vertices at colliders, with a rich variety of possible phenomenology.

Precise estimate of charged Higgsino/Wino decay rate
Journal of High Energy PhysicsHiggsinos and Winos in the supersymmetric Standard Model are prime candidates for dark matter due to their weakly interacting nature. The mass differences between their charged components (charginos) and neutral components (neutralinos) become degenerate
