Ultra-Light Dark Matter in Ultra-Faint Dwarf Galaxies [PDF]

, 2016
Cold Dark Matter (CDM) models struggle to match the observations at galactic scales. The tension can be reduced either by dramatic baryonic feedback effects or by modifying the particle physics of CDM.

Multilepton signatures from dark matter at the LHC

Journal of High Energy Physics, 2022
Leptonic signatures of Dark Matter (DM) are one of the cleanest ways to discover such a secluded form of matter at high energy colliders. We explore the full parameter space relevant to multi-lepton (2- and 3-lepton) signatures at the Large Hadron ...

Searching For Dark Matter Subhalos In the Fermi-LAT Second Source Catalog [PDF]

, 2011
The dark matter halo of the Milky Way is expected to contain an abundance of smaller subhalos. These subhalos can be dense and produce potentially observable fluxes of gamma rays.

Signatures of Majorana dark matter with t-channel mediators

, 2015
Three main strategies are being pursued to search for non-gravitational dark matter signals: direct detection, indirect detection and collider searches.

DarkSUSY - A numerical package for dark matter calculations in the MSSM [PDF]

, 2000
The question of the nature of the dark matter in the Universe remains one of the most outstanding unsolved problems in basic science. One of the best motivated particle physics candidates is the lightest supersymmetric particle, assumed to be the ...

Secluded dark matter in gauged B − L model

Journal of High Energy Physics, 2022
We consider the gauged B − L model which is extended with a secluded dark sector, comprising of two dark sector particles. In this framework the lightest Z $$ \mathcal{Z} $$ 2-odd particle is the dark matter candidate, having a feeble interaction with ...

Off-Diagonal Dark-Matter Phenomenology: Exploring Enhanced Complementarity Relations in Non-Minimal Dark Sectors

, 2017
In most multi-component dark-matter scenarios, two classes of processes generically contribute to event rates at experiments capable of probing the nature of the dark sector.

Detection Rates for Kaluza-Klein Dark Matter [PDF]

, 2002
We consider the lightest Kaluza-Klein particle at N=1 mode (LKP) of universal extra dimension to be the candidate for Dark Matter and predict the detection rates for such particles for Germenium and NaI detectors.

Light in the shadows: primordial black holes making dark matter shine

Journal of High Energy Physics
We consider the possibility of indirect detection of dark sector processes by investigating a novel form of interaction between ambient dark matter (DM) and primordial black holes (PBHs). The basic scenario we envisage is that the ambient DM is “dormant”,

Freezing-in hadrophilic dark matter at low reheating temperatures

Journal of High Energy Physics, 2023
If the reheating temperature at the end of inflation is low, of order 10 MeV, then dark matter produced through ultraviolet freeze-in has a large direct detection cross section. We study such a scenario in which dark matter is hadrophilic.
