Title : "Inflation and Primordial Gravitational Waves beyond Einstein"
Abstract : Recent CMB measurements by the WMAP and Planck collaborations support the inflationary scenario. The simplest inflationary scenario which is based upon a single field, minimally coupled to a gravity, with a flat potential predicts almost Gaussian and nearly scale invariant power spectrum of adiabatic perturbation modes. Considering the accuracy of future observations, in this thesis, we study two inflationary models beyond the standard model and search for their gravitational wave signatures in light of the observational data.
