标题： On the Scale of Inflation

摘要： 由于膨胀的尺度依赖于共形框架，为了完全描述它，应该以理论中所有独立的同时维度无量纲比值来表示其数值。 我们论证了当耦合常数依赖于暴胀场本身时，无法用可测量的量（如张量振幅和当前的普朗克质量）来计算这些比值。 这种不确定性在试图用今天可测量的质量来表达（依赖框架的）暴胀尺度时也变得明显。 虽然我们可以用今天的普朗克质量来计算爱因斯坦框架下的暴胀尺度，但在乔丹框架下却不能这样做。 因此有理由认为张量振幅并不能完全描述暴胀的尺度。 显示英文摘要

摘要： Because the scale of inflation is conformal frame dependent, in order to fully characterize it one should quote its value in terms of all the independent equal-time dimensionless ratios in the theory. We argue that when couplings depend on the inflaton itself, one cannot calculate these ratios in terms of measurable quantities such as the tensor amplitude and the Planck mass at present. This uncertainty also becomes manifest when we try to express the (frame-dependent) inflationary scale in terms of masses that are measurable today. Although we can calculate inflationary scale in the Einstein frame in terms of today's Planck mass, we cannot do the same in the Jordan frame. There are thus grounds to claim that the tensor amplitude does not completely characterize the scale of inflation.
