标题： Possible Signatures of Inflationary Particle Content: Spin-2 Fields

摘要： 我们研究了大质量自旋-2场对暴胀观测量的印记，特别是对一致性关系破坏的影响。 在此设置中，最小暴胀场内容通过dRGT相互作用与大质量自旋-2场相互作用，从而保证了Boulware-Deser鬼态自由度的不存在。 关于自旋粒子的单位性要求，即Higuchi界限，在可观测信号的大小中起着关键作用。 显示英文摘要

摘要： We study the imprints of a massive spin-2 field on inflationary observables, and in particular on the breaking of consistency relations. In this setup, the minimal inflationary field content interacts with the massive spin-2 field through dRGT interactions, thus guaranteeing the absence of Boulware-Deser ghostly degrees of freedom. The unitarity requirement on spinning particles, known as Higuchi bound, plays a crucial role for the size of the observable signal.
