Bispectrum B_eq(k) = B(k,k,k) for equilateral configurations, at redshifts z = 0.35,1, and 3. The symbols are the results from the numerical simulations. We show the bispectrum obtained at tree order (black solid line), standard 1-loop order (blue dot-dashed line), using the full model (red solid line), as well as the 2-halo (cyan dotted line) and 1-halo (cyan dashed line) contributions. The magenta dot-dashed line labeled “Pan” is the phenomenological model of Pan et al. (2007).
