In this thesis we review the particle content of our Universe and its cosmic evolution and show some new physics searches in these two areas. In Part I we present bounds on the energy scale of new physics and couplings of a possible new neutral gauge boson using low energy experiments in the electroweak sector. In Part II we review quantum field theory in curved spacetime and apply some results in cosmology in Part III. In this last part we also show bounds on warm dark matter mass from photometric galaxy surveys.
