Convergence three-point correlation ζ_κ for equilateral configurations (left panel) and third-order moments (middle panel) and (right panel), for sources at redshift z_s = 1. The points are the results from numerical simulations with 3 − σ error bars. The low black dashed line “L” is the lowest-order perturbative prediction (27), the “1-loop” dash-dotted black line is the prediction of one-loop standard perturbation theory, which is identified with our three-halo term, the blue dotted line “2H” is the two-halo contribution and the upper blue dashed line “1H” is the one-halo contribution. The red solid line is our full model.
