Abstract
Summary: ``We discuss implications of the latest BICEP/Keck data release for inflationary models, with special emphasis on the cosmological attractors which can describe all presently available inflation-related observational data. These models are compatible with any value of the tensor to scalar ratio $r$, all the way down to $r = 0$. Some of the string theory motivated models of this class predict $10^{-3} \leq r\leq10^{-2}$. The upper part of this range can be explored by the ongoing BICEP/Keck observations.''
