论文摘要
我们证明，从宇宙背景辐射（CMB）的观察值（CMB）观察值中，对通货膨胀可观察物的最新限制，即张量与量表比$ r $ $ r $和标量光谱指数$ n _ {_ s} $。负耦合常数的情况需要特殊治疗。
We demonstrate that the latest constraints on inflationary observables, namely the tensor-to-scalar ratio $r$ and the scalar spectral index $n_{_S}$, from the Cosmic Background Radiation (CMB) observations are already strong enough to rule out the model of a scalar field with a power law potential even in the presence of kinetic coupling to gravity with a positive coupling constant. The case for a negative coupling constant needs special treatment.
