论文摘要
如果通货膨胀能量表足够高，则对有效重力作用的更高呈矫正可能会在原始张量扰动中留下特征。在本文中，我们进一步研究了在结构对称性最小破裂的模型中，充气场与高曲率张量的耦合的影响。我们表明，可观察到的较高量张量的张量一致性关系的违规行为也意味着张量倾斜度的运行也相对较大，即使相对于标准慢速滚动案例，即使有一定的数量级也增强了。这可能会在张量的两点函数中留下签名，我们可以测试以识别更高曲线的效果，最重要的是，如果将未来的引力波实验可见为蓝色的倾斜光谱。利用当前的宇宙微波背景和重力波数据，我们还对通货膨胀参数产生了约束，推断出大型高源性校正似乎不受欢迎。
Higher-curvature corrections to the effective gravitational action may leave signatures in the spectrum of primordial tensor perturbations if the inflationary energy scale is sufficiently high. In this paper we further investigate the effects of a coupling of the Inflaton field to higher-curvature tensors in models with a minimal breaking of conformal symmetry. We show that an observable violation of the tensor consistency relation from higher-curvature tensors implies also a relatively large running of the tensor tilt, enhanced even by some order of magnitude with respect to the standard slow roll case. This may leave signatures in the tensor two-point function that we could test to recognize higher-curvature effects, above all if they are translated into a blue tilted spectrum visible by future Gravitational Wave experiments. Exploiting current cosmic microwave background and gravitational wave data we also derive constraints on the inflationary parameters, inferring that large higher-curvature corrections seem to be disfavored.
