Title Calculating the Bispectrum in Non-Canonical Multi-field Inflation
Abstract We extend the transport framework for numerically evaluating the power spectrum and bispectrum in multi-field inflation to the case of a curved field- space metric. This method naturally accounts for all sub and super-horizon tree level effects, including those induced by the curvature of the field-space. We present a working open source implementation of our equations in an extension of the publicly available PyTransport code. Finally we illustrate the utility of our work when applied to examples of inflationary models with a non-trivial field- space metric.
