Searching for dark matter signals with high energy astrophysical neutrinos in IceCube
Khushboo Dixit, Gopolang Mohlabeng, Soebur Razzaque
High-energy neutrinos provide a potentially powerful and distinctive probe for dark matter (DM) - neutrino interactions, particularly in environments with enhanced DM densities, su…
X-rays from Inelastic Dark Matter Freeze-in
Gordan Krnjaic, David McKeen, Riku Mizuta +3
We study inelastic dark matter produced via freeze-in through a light mediator with a mass splitting below the electron-positron threshold. In this regime, the heavier dark matter…
Direct Detection of Fast-Moving Low-Mass Dark Matter
Haider Alhazmi, Doojin Kim, Kyoungchul Kong +3
We examine the signals produced by dark matter interactions with electrons, which play a crucial role in direct detection experiments employing heavy target materials, particularly…
Boxed in from all sides: a global fit to loopy dark matter and neutrino masses
Karen Macías Cárdenas, Gopolang Mohlabeng, Aaron C. Vincent
We investigate a dark matter model that couples to the standard model through a one-loop interaction with neutrinos, where the mediator particles also generate neutrino masses. We…
Loosely Bound Composite Dark Matter
Javier F. Acevedo, Yilda Boukhtouchen, Joseph Bramante +3
We investigate loosely bound composite states made of dark matter, where the binding energy for constituent particles is less than the constituent mass. We focus on models of nucle…
Radiative Corrections to Light Thermal Pseudo-Dirac Dark Matter
Gopolang Mohlabeng, Adreja Mondol, Tim M. P. Tait
Light thermal dark matter has emerged as an attractive theoretical possibility and a promising target for discovery at experiments in the near future. Such scenarios generically in…
Cosmic Ray-Boosted Dark Matter at IceCube
Christopher Cappiello, Qinrui Liu, Gopolang Mohlabeng +1
Cosmic ray (CR) upscattering of dark matter is considered as one of the most straightforward mechanisms to accelerate ambient dark matter, making it detectable at high threshold, l…
Directional Neutrino Searches for Galactic Center Dark Matter at Large Underground LArTPCs
Matthew R. Buckley, Andrew Mastbaum, Gopolang Mohlabeng
We investigate the sensitivity of a large, underground LArTPC-based neutrino detector to dark matter in the Galactic Center annihilating into neutrinos. Such a detector could have…
Light Dark Matter Accumulating in Planets: Nuclear Scattering
Joseph Bramante, Jason Kumar, Gopolang Mohlabeng +2
We present, for the first time, a complete treatment of strongly-interacting dark matter capture in planets, taking Earth as an example. We focus on light dark matter and the heati…
Report of the Topical Group on Particle Dark Matter for Snowmass 2021
Jodi Cooley, Tongyan Lin, W. Hugh Lippincott +71
This report summarizes the findings of the CF1 Topical Subgroup to Snowmass 2021, which was focused on particle dark matter. One of the most important scientific goals of the next…
Why should the U.S. care about high energy physics in Africa and Latin America?
Kétévi A. Assamagan, Carla Bonifazi, Johan Sebastian Bonilla Castro +6
Research, education and training in high energy physics (HEP) often draw international collaborations even when priorities and long term visions are defined regionally or nationall…
Snowmass2021 Cosmic Frontier White Paper: Ultraheavy particle dark matter
Daniel Carney, Nirmal Raj, Yang Bai +25
We outline the unique opportunities and challenges in the search for "ultraheavy" dark matter candidates with masses between roughly and the Planck scale $m_{\rm pl}…
Studying dark matter with MadDM 3.1: a short user guide
Chiara Arina, Jan Heisig, Fabio Maltoni +4
MadDM is an automated numerical tool for the computation of dark-matter observables for generic new physics models. We announce version 3.1 and summarize its features. Notably, the…
Implications of the XENON1T Excess on the Dark Matter Interpretation
Haider Alhazmi, Doojin Kim, Kyoungchul Kong +3
The dark matter interpretation for a recent observation of excessive electron recoil events at the XENON1T detector seems challenging because its velocity is not large enough to gi…
Getting a THUMP from a WIMP
Hooman Davoudiasl, Gopolang Mohlabeng
Producing an acceptable thermal relic abundance of dark matter with masses TeV is a challenge. We propose a novel mechanism where GeV-scale states establish a tiny therm…
Direct Detection Anomalies in light of Data
Matthew R. Buckley, Gopolang Mohlabeng, Christopher W. Murphy
Measurements from the Gaia satellite have greatly increased our knowledge of the dark matter velocity distributions in the Solar neighborhood. There is evidence for multiple cold s…
Revisiting the Dark Photon Explanation of the Muon Anomalous Magnetic Moment
Gopolang Mohlabeng
A massive gauge boson known as a "dark photon" or , has long been proposed as a potential explanation for the discrepancy observed between the experimen…
GeV-Scale Messengers of Planck-Scale Dark Matter
Hooman Davoudiasl, Gopolang Mohlabeng
If dark matter (DM) originates from physics near the Planck scale it could be directly detected via its multiple scattering signals, yet this requires a large cross section for DM…

Federico Ambrogi, Chiara Arina, Mihailo Backovic +5
We present MadDM v.3.0, a numerical tool to compute particle dark matter observables in generic new physics models. The new version features a comprehensive and automated framework…
Galactic Dark Matter Population as the Source of Neutrino Masses
Hooman Davoudiasl, Gopolang Mohlabeng, Matthew Sullivan
We propose that neutrino masses can be zero and may be generated by the local distribution of dark matter through a feeble long range scalar force. We discuss potential…
Electroweak Kaluza-Klein Dark Matter
