Hints of dark matter-neutrino interactions in Lyman- data

DC Hooper, M Lucca - Physical Review D, 2022 - APS
In this work we investigate the possibility that dark matter and (massive) neutrinos can
interact via a simple, constant cross section. Building on previous numerical efforts, we …

S8 tension in the context of dark matter–baryon scattering

A He, MM Ivanov, R An… - The Astrophysical Journal …, 2023 - iopscience.iop.org
We explore an interacting dark matter (IDM) model that allows for a fraction of dark matter
(DM) to undergo velocity-independent scattering with baryons. In this scenario, structure on …

Not as big as a barn: Upper bounds on dark matter-nucleus cross sections

MC Digman, CV Cappiello, JF Beacom, CM Hirata… - Physical Review D, 2019 - APS
Critical probes of dark matter come from tests of its elastic scattering with nuclei. The results
are typically assumed to be model independent, meaning that the form of the potential need …
