Journal ArticleDOI
Supersymmetric cold dark matter with Yukawa unification
TL;DR: In this paper, the cosmological relic density of the lightest supersymmetric particle under the assumption of gauge and Yukawa coupling unification is calculated under the universal boundary conditions from gravity-mediated supersymmetry breaking.
Journal ArticleDOI
Yukawa Unification, b --> s gamma and Bino-Stau Coannihilation
TL;DR: In this article, the authors considered the minimal supersymmetric standard model with universal boundary conditions and "asymptotic" Yukawa unification, and calculated the relic abundance of the light-est super-particle (bino) by including its coannihilations with the next-to-lightest superpartner (lightest stau).
Journal ArticleDOI
Yukawa unification, b→sγ and bino–stau coannihilation
TL;DR: In this article, the authors considered the minimal supersymmetric standard model with universal boundary conditions and "asymptotic" Yukawa unification and calculated the relic abundance of the lightest supersymmymmetric particle (bino) by including its coannihilations with the next-to-lightest super-stau particle (lightest stau).
Journal ArticleDOI
Yukawa quasi-unification
TL;DR: In this paper, the authors constructed concrete supersymmetric grand unified theories based on the Pati-Salam gauge group SU(4)c×SU(2)L×SU (2)R which naturally lead to a moderate violation of theasymptotic Yukawa unification and thus can allow an acceptable b-quark mass even with universal boundary conditions.
Journal ArticleDOI
Quintessential kination and cold dark matter abundance
TL;DR: In this article, the decoupling of a thermal cold dark matter particle during the period of kination is analyzed, and the relic density is calculated both numerically and semi-analytically.
