Dark matter from "strong gravity" - consistent with CRESST, CoGeNT and DAMA/LIBRA

TL;DR

This paper proposes a 'strong gravity' model for dark matter particles with masses between 10.5 and 17.5 GeV, aligning with experimental detection results and astrophysical constraints.

Contribution

It introduces a consistent dark matter model based on strong gravity that aligns with multiple experimental and astrophysical observations.

Findings

Dark matter particle mass range 10.5-17.5 GeV

Compatibility with CRESST, CoGeNT, DAMA/LIBRA results

Alignment with supermassive black hole formation constraints

Abstract

Kelso, Hooper and Buckley [arXiv:1110.5338] found CRESST, CoGeNT and DAMA/LIBRA results are consistent with 10 - 15 GeV dark matter particles. Hennawi and Ostriker [arXiv:astro-ph/0108203] analyzed supermassive black hole formation in the centers of galaxies, finding a best fit for dark matter (self-interaction cross-section)/mass ratio = 0.02 cm^{2}/g, with round-off error of 25%. Combining the Hennawi/Ostriker result with the "strong gravity" model for dark matter [arXiv:0706.3050] requires dark matter particles with mass between 10.5 GeV and 17.5 GeV, overlapping the Kelso/Hooper/Buckley dark matter particle mass range.
