We study the effects of the nonminimal derivative coupling on the dissipative dynamics of the warm inflation where the scalar field is nonminimally coupled to gravity via its kinetic term.

| Summary: | We study the effects of the nonminimal derivative coupling on the dissipative
dynamics of the warm inflation where the scalar field is nonminimally coupled to
gravity via its kinetic term. We present a detailed calculation of the cosmological
perturbations in this setup. We use the recent observational data from the joint
data set of WMAP9 + BAO + H0 and also the Planck satellite data to constrain our
model parameters for natural and chaotic inflation potentials. We study also the
levels of non-Gaussianity in this warm inflation model and we confront the result
with recent observational data from the Planck satellite. |
