Limits on New Superweakly Interacting Particles from Primordial Nucleosynthesis
TLDR
In this paper, it was shown that the maximum number of superweakly interacting, light (< 1 MeV) particles is between ∼1 and ∼20, depending on the strength of their interaction.About:

Cosmic abundances of stable particles: Improved analysis
TL;DR: An exact relativistic single-integral formula for the thermal average of the annihilation cross section times velocity, the key quantity in the determination of the cosmic relic abundance of a species, is obtained in this paper.

micrOMEGAs_3: A program for calculating dark matter observables
TL;DR: This new version of micrOMEGAs is a major update which includes a generalization of the Boltzmann equations to accommodate models with asymmetric dark matter or with semi-annihilation and a first approach to a generalizations of the thermodynamics of the Universe in the relic density computation.

micrOMEGAs : A program for calculating the relic density in the MSSM
TL;DR: In this article, a code that calculates the relic density of the lightest supersymmetric particle (LSP) in the minimal supersymmymmetric standard model is presented, where all tree level processes for the annihilation of the LSP are included as well as all possible coannihilation processes with neutralinos, charginos, sleptons, squarks and gluinos.

Superdense Matter: Neutrons Or Asymptotically Free Quarks?
John Collins,Malcolm J. Perry +1 more
TL;DR: The quark model implies that superdense matter (found in neutron star cores, exploding black holes, and the early big-bang universe) consists of quarks rather than of hadrons as discussed by the authors.

Cosmological Limits to the Number of Massive Leptons
TL;DR: In this article, it was shown that observational limits to the primordial abundance of 4He lead to the constraint that the total number of types of heavy lepton must be less than or equal to 5.
