A physicist’s code

• CosmoEFT: Calculating 1 & 2-loop IR-safe power spectra for realistic cosmologies. (c++) Hosted here

  • Uses Copter to map from transfer function + cosmology to linear powerspectrum.

  • Uses the Monte-Carlo integration library CUBA.

  • Originally developed in a project with Daniel Green, Simon Forman, and Leonardo Senatore towards precision EFTofLSS predictions at two-loops. Updated later to expand around Planck Best-fit Cosmology by M. Cataneo and S. Forman for this paper. Currently maintained by M. Cataneo.

• See also other useful EFT code Leonardo has curated / been involved with: here, esp. towards resumming in the IR.

• If there’s pedagogic interest, I can upload some early Mathematica code for EFT of LSS at 1-loop including exact time evolution.

• some other relevant EFTofLSS papers:

  • Establishing the EFT
  • IR-safe two-loop power spectrum
  • EFT at two-loops

Related to scattering amplitudes, unitarity, and double-copy.

• ampGraphTools: Mathematica library for graph manipulation/dressing esp towards multiloops. Hosted here.
  • I use this for pretty much any amplitudes calculation. Working it’s way towards documentation and actual public release. Feel free to poke around.
• some relevant amplitudes papers:
  • TASI 2014 lecture notes.
  • State sums in 4D for SUSY gauge theories
  • Double-copy at loop level
  • Color-kinematics and \((n-3)!\)(BCJ) Relations
