影子暗物质候选者的残余密度

The relic density of shadow dark matter candidates

Mehrdad Adibzadeh, P. Q. Hung

摘要:

本文给出了冷暗物质候选者的残余密度的计算结果,它来自一个暗能量和暗物质的模型,该模型由一个渐近自由规范群SU(2)Z(QZD)描述,在很低的尺度下(λ Z ~ 10^(-3)eV),耦合常数α Z ~ 1,而在高能时α Z ~弱耦合. QZD的暗物质候选者是两个相互作用较弱的大质量粒子形式的费米子。我们的研究结果表明,对于质量在50和285 GeV之间的暗物质,它们可以解释宇宙中相当大的一部分或整个暗物质。

英文摘要:

We present the results of relic density calculations for cold dark matter candidates coming from a model of dark energy and dark matter, which is described by an asymptotically free gauge group SU(2)_Z (QZD) with a coupling constant alpha_Z ~ 1 at very low scale of Lambda_Z ~ 10^(-3) eV while alpha_Z ~ weak coupling at high energies. The dark matter candidates of QZD are two fermions in the form of weakly interacting massive particles. Our results show that for masses between 50 and 285 GeV, they can account for either a considerable fraction or the entire dark matter of the Universe.
