Full bispectra from primordial scalar and tensor perturbations in the most general single-field inflation model

Résumé

We compute the full bispectra, namely both auto and cross bispectra, of primordial curvature and tensor perturbations in the most general single-field inflation model whose scalar and gravitational equations of motion are of second order. The formulae in the limits of k-inflation and potential-driven inflation are also given. These expressions are useful for estimating the full bispectra of temperature and polarization anisotropies of the cosmic microwave background radiation.
