论文摘要
我们使用Planck 2018和WMAP数据来限制由标量场$ ϕ $驱动的通货膨胀模型，在存在非微鳞片展混合项$ \ frac {1} {2}ξrϕ^2 $的情况下。我们考虑了四个不同的标量场电位$ ϕ^p e^{ - λϕ}，〜（1 - ϕ^{p}）我们计算潜在的慢速参数，并预测潜在的参数（$λ，p，α$）空间的标量光谱$ n_s $和张量表$ r $ r $。我们将我们的结果与文献中存在的结果进行了比较，这表明Planck 2018数据发布后，非最低通货膨胀的现状。
We use the PLANCK 2018 and the WMAP data to constraint inflation models driven by a scalar field $ϕ$ in the presence of the non-minimal scalar-curvature mixing term $\frac{1}{2}ξR ϕ^2$. We consider four distinct scalar field potentials $ϕ^p e^{-λϕ},~(1 - ϕ^{p})e^{-λϕ},~(1-λϕ)^p$ and $\frac{αϕ^2}{1+αϕ^2}$ to study inflation in the non-minimal gravity theory. We calculate the potential slow-roll parameters and predict the scalar spectral index $n_s$ and the tensor-to-scalar ratio $r$, in the parameters ($λ, p, α$) space of the potentials. We have compared our results with the ones existing in the literature, and this indicates the present status of non-minimal inflation after the release of the PLANCK 2018 data.
