论文摘要
我们解释了Cobe，WMAP和Planck卫星任务在宇宙微波背景中观察到的缺乏大角度的温度相关性和明显的均匀偶然性不平衡，这是最终是由复合膨胀的膨胀式磁场（例如，菲尔米米离子凝结物）最终引起的。基于因果关系论证和对角度两点相关函数的傅立叶分析，两个红外临界值$ k _ {\ rm min}^{\ rm甚至在CMB Power Spectrum中引入了与周期性和反式边界条件相关的CMB Power Spectrum（奇数} $）超声理论），不诉诸于任何特定模型。
We interpret the lack of large-angle temperature correlations and the apparent even-odd parity imbalance, observed in the cosmic microwave background by COBE, WMAP and Planck satellite missions, as a possible stringy signal ultimately stemming from a composite inflaton field (e.g. a fermionic condensate). Based on causality arguments and a Fourier analysis of the angular two-point correlation function, two infrared cutoffs $k_{\rm min}^{\rm even,odd}$ are introduced in the CMB power spectrum associated, respectively, with periodic and antiperiodic boundary conditions of the fermionic constituents (echoing the Neveu-Schwarz-Ramond model in superstring theory), without resorting to any particular model.
