Understanding the properties of dark matter has proved to be one of the most challenging problems of particle phenomenology. In this paper, we have tried to understand the phenomenology of dark matter in light of very well understood properties of cosmic microwave background (CMB) anisotropy. To connect these two, inflation and its subsequent evolution known as the reheating phase play the important role. Following the previous analysis, we first established a one-to-one correspondence between the CMB power spectrum and the reheating temperature assuming the perturbative reheating scenario. Further by incorporating a possible dark matter candidate through the radiation annihilation process during reheating and the current value of dark matter abundance, we constrain the dark matter parameter space through the inflationary power spectrum for different inflationary models.

Photon-neutrino interaction in theta-exact covariant noncommutative model: Phenomenology and Quantum properties*
我们构造了θ-精确协变非对易(NC)模型,并分别从中微子-核子非弹性散射(nuN-> nu+X)、等离子体衰变为中微子对(gamma_pl -> bar nu + nu)、BBN核合成和暴胀后的再加热阶段得到了NC尺度(Lambda_NC)上的各种封闭约束.我们已经找到了中微子两点函数的封闭形式。它显示了UV发散项与软化的UV/IR混合项以及与有限项的解耦。我们发现,有问题的UV发散和UV/IR混合项消失的非对易参数θ,保持酉性的一定的选择。我们发现非微扰修改的中微子色散关系,这是渐近独立的非对易性的规模在低和高能量的限制,并可能允许超光速传播。

Theory and Phenomenology of Planckian Interacting Massive Particles as Dark Matter
普朗克相互作用暗物质(Planckian Interacting Dark Matter,PIDM)是暗物质的一个最小场景,假设只有与标准模型的引力相互作用,并且只有一个自由参数,PIDM质量。如果再加热温度足够高,在膨胀后的标准模型扇区的热等离子体中,通过引力散射可以成功地产生PIDM,PIDM的质量范围从TeV到GUT尺度。最小假设的一个大统一体规模PIDM质量可以在未来测试的原始张量标量比的测量。当大的原始张量模在大质量范围内与作为暗物质的QCD轴子处于紧张状态时,它将有利于PIDM作为WIMP的最小替代品。在这里,我们概括了以前研究的标量PIDM方案的费米子,矢量和张量PIDM方案的情况下,并表明,现象几乎是相同的,独立的自旋的PIDM。我们还考虑具体实现的PIDM的卡鲁扎克莱因激发的引力子在轨道紧化的弦论,以及在模型的单值膨胀和希格斯膨胀。最后讨论了通过非微扰衰变间接探测PIDM的可能性。
