Weakly-Interacting Massive Particles in Torsionally-Gravitating Dirac Theory

TL;DR

This paper explores how torsion in gravity theories coupled with Dirac fields could influence dark matter behavior, especially if WIMPs form condensates, potentially affecting galactic-scale phenomena.

Contribution

It introduces the idea that torsionally-gravitating Dirac fields can have significant implications for dark matter, particularly through WIMP condensates at galactic scales.

Findings

Torsion effects may be relevant at galactic scales.

Dirac fields with torsion exhibit properties impacting dark matter models.

Potential observable consequences for dark matter distribution.

Abstract

We shall consider the problem of Dark Matter in torsion gravity with Dirac matter fields; we will consider the fact that if WIMPs in a bath are allowed to form condensates then torsional effects may be relevant even at galactic scales: we show that torsionally-gravitating Dirac fields have interesting properties for the problem of DM. We discuss consequences.
