ABSTRACT The discrepancy between the weak lensing (WL) and the Planck measurements of S8 has been a subject of several studies. Assuming that residual systematics are not the cause, these studies tend to show that a strong suppression of the amplitude of the mass power spectrum P(k) in the late Univ...
