An intriguing possibility for dark matter is considered: the dark matter is charged with respect to ''dark'' gluons of a new non-Abelian gauge theory. The gluons constitute self-interacting dark radiation. Cosmological consequences and distinctive experimental signatures are explored.

Neutrino decoupling beyond the Standard Model: CMB constraints on the Dark Matter mass with a fast and precise Neff evaluation (2018, background): “The agreement between the observations of the Cosmic Microwave Background (CMB) [1, 2], and the primordial element abundances [3, 4] with the SM prediction [5–15] of three relativistic neutrino species represents a success of the Standard Model, and constitues a non-trivial test for some of its exte”
Constraints on neutrinos and WDM Hints, neutrino bounds and WDM constraints from SDSS DR14 Lyman-$\alpha$ and Planck full-survey data (2019, methodology): “An example of a mechanism leading to a small reduction of the effective slope of the matter power spectrum d lnPm d ln k is provided by the scattering dark matter model of [67].”
Evidence for dark matter interactions in cosmological precision data? (2015, methodology): “In [15] it was shown that the DM in this model obtains the correct abundance from thermal freeze-out for masses 1.”
Precision early universe thermodynamics made simple: Neff and neutrino decoupling in the Standard Model and beyond (2020, methodology): “For example, the method could be used to study: late dark matter decoupling [76], generic dark sectors [77, 78], dark sectors equilibrating during BBN [79], or the BBN era in low-scale Baryogenesis set-ups [80–83].”
Interacting dark sector and precision cosmology (2017, methodology): “One can either have all of the DM interact very weakly with the DR [10] or have very little IDM but with strong couplings to the DR so that they form a tightly coupled “dark plasma” [14, 22].”

CMB-S4 Science Case, Reference Design, and Project Plan (2019, background): “A radiation fluid whose fluctuations do not exceed the sound speed of the plasma [179, 180] could arise from large neutrino self-interactions [181, 182, 183, 184, 185], neutrino-dark sector interactions [186, 187], or dark radiation self-coupling [188, 189, 190].”
Evidence for a sublattice weak gravity conjecture (2016, background): “Dark matter coupled to nonabelian dark radiation can damp the matter power spectrum in a specific way [50–52] that has been argued to improve fits to observation by 3σ [51].”
