Equipped with the rich data from recent CMB missions, in particular, Planck, it has become possible to reconstruct the Primordial Power Spectrum in a model-Independent non-parametric manner allowing us to relax the ...

Both Conformal and Boostless Bootstrap techniques have been applied by many in the literature to compute pure scalar and graviton inflationary correlators. In this thesis, our focus will primarily be on mixed graviton and ...
