Another approach is to assume that a consistent gravitational EFT also contains the Weyl-squared term and to study its impact on inflationary observables [20]. Related analyses argue that small corrections can substantially shift predictions of Starobinsky-like attractor models into the ACT-preferred region [22]. All of these approaches are well motivated and can account for certain phenomenology of quantum effects, but they do not uniquely specify which operators must appear once a particular microscopic theory is fixed. It is crucial to note that in most of the existing literature, the dominant quantum effects are assumed to come frommatterloops.
