The two-loop bispectrum in the effective theory of large-scale structure
  We study the bispectrum of large-scale structure in the EFTofLSS including
corrections up to two-loop. We derive an analytic result for the double-hard
limit of the two-loop correction, and show that the UV-sensitivity can be
absorbed by the same four EFT operators that renormalize the one-loop
bispectrum. For the single-hard region, we employ a simplified treatment,
introducing one extra EFT parameter. We compare our results to N-body
simulations, and show that going from one- to two-loop extends the wavenumber
range with percent-level agreement from $k \simeq 0.08$ to
$0.15~h/\mathrm{Mpc}$.
