Abstract
Measurement of mode-coupling kernel of large-scale structure (LSS): K(k,q) qδPn1(k)/ΔP0 (q) Unlike the standard PT results, • There appears UV suppression in N-body simulation at k<<q • Discrepancy can be seen even at low-k, where standard PT can reproduce the N-body result quite well Physical origin A connection with small-scale physics (formation and merging processes of dark matter halos) Implication Check the validity and limitation for EFTofLSS → A step toward an improved prescription of LSS.
