TL;DR: In this paper, a detailed exploration of neutralino-stau ( χ − τ ) coannihilation channels is presented, including analytical expressions and numerical results. And the implications of coannihilations for the cosmological relic density of the LSP, which is assumed to be stable, in the constrained minimal supersymmetric extension of the Standard Model (CMSSM), in which the soft supersymmetry-breaking parameters are universal at the supergravity GUT scale.

TL;DR: In this article, the effects of neutralino-stau ( χ− τ ) coannihilations on the cosmological relic density of the lightest supersymmetric particle (LSP) χ in the minimal superymmetric extension of the Standard Model (MSSM), particularly in the constrained MSSM, were considered.

TL;DR: In this paper, the effects of neutralino-stau coannihilations on the cosmological relic density of the lightest supersymmetric particle (LSP) in the minimal supergravity extension of the Standard Model (MSSM), particularly in the constrained MSSM in which universal supergravity inputs at the GUT scale are assumed.

TL;DR: In this article, the authors calculate the relic density of very heavy, stable scalar neutrinos in the minimal supersymmetric standard model, including all two-body final states, as well as the effects of co-annihilation with scalar electrons.

TL;DR: In this paper, the authors explore the parameter space of the minimal supersymmetric extension of the Standard Model (MSSM), allowing the soft supersymmetry-breaking masses of the Higgs multiplets, m1,2, to be non-universal (NUHM).
