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 ...

Dark Matter Halos as Particle Colliders: Unified Solution to Small-Scale Structure Puzzles from Dwarfs to Clusters. [PDF]

open access: yesPhysical Review Letters, 2015
Astrophysical observations spanning dwarf galaxies to galaxy clusters indicate that dark matter (DM) halos are less dense in their central regions compared to expectations from collisionless DM N-body simulations.

Erratum to: Wino-like Minimal Dark Matter and future colliders [PDF]

open access: yesJournal of High Energy Physics, 2014
We extend the Standard Model with an EW fermion triplet, stable thanks to one of the accidental symmetries already present in the theory. On top of being a potential Dark Matter candidate, additional motivations for this new state are the stability of ...

Phenomenology of $U(1)_{L_\mu - L_\tau}$ charged dark matter at PAMELA/FERMI and colliders [PDF]

open access: yes, 2008
Recent data on $e^+/e^-$ and $\bar{p}$ cosmic rays suggest that dark matter annihilate into the standard model (SM) particles through new leptophilic interaction. In this paper, we consider a standard model extension with the gauged $U(1)_{L_\mu - L_\tau}

Probing the baryogenesis and dark matter relaxed in phase transition by gravitational waves and colliders [PDF]

open access: yes, 2017
The cosmological phase transition with Q-balls production mechanism can explain the baryogenesis and dark matter simultaneously, where constraints on dark matter masses and reverse dilution are significantly relaxed.

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.

Cosmic particle colliders: simulations of self-interacting dark matter with anisotropic scattering [PDF]

open access: yes, 2016
We investigate how self-interacting dark matter (SIDM) with anisotropic scattering affects the evolution of isolated dark matter haloes as well as systems with two colliding haloes.

Numerical Model and Experimental Validation of Composite Metal Foam in Protecting Carbon Steel Against Puncture

open access: yesAdvanced Engineering Materials, EarlyView.
The puncture prevention and energy absorption performance of composite metal foam (CMF) are studied experimentally and numerically for hazardous materials transportation protection. The numerical model implementing air within the CMF (nonhomogeneous model using fluid cavity technique) predicts puncture more accurately compared to the homogeneous CMF ...

Precise estimate of charged Higgsino/Wino decay rate

open access: yesJournal of High Energy Physics
Higgsinos 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
