论文摘要
我们分析了宇宙微波背景（CMB）数据，这些数据考虑了依赖动量的有效音速（MYS）的影响。这种方法允许以独立模型的方式研究原始熵的效果，其实现需要对现有的CMB拟合数值代码最小化，为单量表场模型开发。 我们采用了一种现象学方法，并研究了范围周围杂物的局部变化，其他分析表明与大致规模不变的曲率扰动光谱差异。我们可以在没有混乱的模型方面对拟合度进行了实质性改进，这表明以混乱为模型的原始熵可以解释这些偏差。
We analyze cosmic microwave background (CMB) data taking into account the effects of a momentum dependent effective sound speed (MESS). This approach allows to study the effects of primordial entropy in a model independent way, and its implementation requires a minimal modification of existing CMB fitting numerical codes developed for single scalar field models. We adopt a phenomenological approach, and study the effects a local variation of the MESS around the scale where other analysis have shown some deviation from an approximately scale invariant curvature perturbation spectrum. We obtain a substantial improvement of the fit with respect to a model without MESS, showing that primordial entropy modeled by MESS can be an explanation of these deviations.
