The dashed lines are the ratios of the “renormalized” perturbative terms of the expansion (24) to the nonlinear “sticky model” power spectrum, , for n = 1 to 5 and n = 10,15,20,30,50, and 70. The solid line is the ratio of the nonperturbative correction to the nonlinear power spectrum, P_s.c.(k)/P_sticky(k). The four panels correspond to redshifts z = 0,1,2, and 3 (with a shift of the plot towards higher k at higher z).
