3-point functions in canonical inflation

step_shape

PyTransport and CppTransport are automated tools that compute the two- and three-point correlation functions for field-space, tensor and curvature perturbations produced by arbitrary multiple-field inflationary models with canonical kinetic terms.

PyTransport is a Python platform developed by a team at Queen Mary, University of LondonCppTransport is a C++ platform developed by a team at the University of Sussex.

Both tools can compute the statistical properties of the inflationary perturbations directly from the inflationary potential. They both accurately compute the amplitude, shape and scale dependence of the power spectrum and bispectrum. Each package has different strengths and is suitable for different use cases. PyTransport is lightweight and easily scriptable. CppTransport provides a more managed environment, including automated parallelization of large calculations.
