论文摘要
众所周知，通过在这些时期期间的充气和重力场的各种动力学，通货膨胀的动力学留下了可观察到的烙印。这里强调的是，其他粒子的自由度也能够在原始观察物上留下烙印，如果它们在通货膨胀的时期内成为非相关主义后的灭绝后传递熵，则可以将其烙印留在原始的观测值上。其他颗粒的这种an灭将导致在枢轴尺度上降低张量与尺度比率（并且最大程度的尺度尺度大于此），这将有助于根据当前的观测值将这些电势恢复，而这些观测值否则会产生较大的张量量比比率。
Pre-inflationary dynamics is known to have left observable imprints via the varied dynamics of the inflaton and the graviton fields during those epochs. It is highlighted here that other particle degrees of freedom, too, are capable of leaving their imprints on primordial observables if they transfer their entropies upon annihilation after becoming non-relativistic during a pre-inflationary epoch. Such annihilations of other particles would result in lowering of the tensor-to-scalar ratio at the pivot scale (and at length scales larger to that) which would help bring those potentials back in accordance with current observations which are otherwise disfavoured for yielding large tensor-to-scalar ratios at present.
