摘要:

最近的BICEP/Keck宇宙微波背景数据,结合以前的WMAP和普朗克数据,施加强有力的新的约束倾斜的标量扰动谱,$n_s$,以及张量标量比,$r$。这些约束的膨胀,$N_*$,膨胀耦合到物质,$y$,和再加热温度,$T_{\rm reh}$,我们评估的吸引子模型制定的通货膨胀,在无标度超引力的数量的e倍。68% C. L。$(n_s, r)$区域有利于大的$N_*, y$和$T_{\rm reh}$值,这受到引力子和超对称暗物质产生的限制。

英文摘要:

Recent BICEP/Keck data on the cosmic microwave background, in combination with previous WMAP and Planck data, impose strong new constraints on the tilt in the scalar perturbation spectrum, $n_s$, as well as the tensor-to-scalar ratio, $r$. These constrain the number of e-folds of inflation, $N_*$, the magnitude of the inflaton coupling to matter, $y$, and the reheating temperature, $T_{\rm reh}$, which we evaluate in attractor models of inflation as formulated in no-scale supergravity. The 68% C.L. region of $(n_s, r)$ favours large values of $N_*, y$ and $T_{\rm reh}$ that are constrained by the production of gravitinos and supersymmetric dark matter.
