Nevertheless, even for ΛCDM initial spectra, the fact that the two-loop result approaches the SPT limit only very slowly when increasing kσ (see blue and black solid lines in Fig

Note that this would be different for scaling models for which the one-, two-loop integrals are UV divergent in SPT, since they feature relevant contributions to the loop integral within VPT forp,q∼kσ no matter how largekσ is
