Towards Quantum-Dot Detectors as Barcodes for Dark Matter Interactions
Marek Matas, Andrea Gallo Rosso, Antonio Cammarata +6
Quantum dots are tunable semiconductor nanocrystals that can be produced at industrial scales. We present the first ab initio calculation of the scattering of dark matter on electr…
Strong Constraints on Dark Photon and Scalar Dark Matter Decay from INTEGRAL and AMS-02 data
Thong T. Q. Nguyen, Isabelle John, Tim Linden +1
We investigate the decay of bosonic dark matter with masses between 1 MeV and 2 TeV into Standard Model final states. We specifically focus on dark photons that kinetically mix wit…
Super-Kamiokande Strongly Constrains Leptophilic Dark Matter Capture in the Sun
Thong T. Q. Nguyen, Tim Linden, Pierluca Carenza +1
The Sun can efficiently capture leptophilic dark matter that scatters with free electrons. If this dark matter subsequently annihilates into leptonic states, it can produce a detec…
The Sun Can Strongly Constrain Spin-Dependent Dark Matter Nucleon Scattering Below the Evaporation Limit
Thong T. Q. Nguyen, Tim Linden
The Sun is a promising target for dark matter (DM) searches due to its ability to accumulate DM particles via scattering and catalyze their self-annihilation. However, at low DM ma…
Gamma-Ray Observations of Galaxy Clusters Strongly Constrain Dark Matter Annihilation in Prompt Cusps
Milena CrnogorÄeviÄ, M. Sten Delos, Nadia Kuritzén +1
Thermal dark matter models generically include the prompt creation of highly-concentrated dark matter cusps in the early Universe. Recent studies find that these cusps can survive…
X-Ray Constraints on Dark Photon Tridents
Tim Linden, Thong T. Q. Nguyen, Tim M. P. Tait
Dark photons that are sufficiently light and/or weakly-interacting represent a compelling vision of dark matter. Dark photon decay into three photons, which we call the dark photon…
