  3. 2. Higgs inflation

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Erik Schildt; [2018]
    Keywords : inflation; Higgs inflation; nonminimal coupling; conformal transformation; Higgs cosmology; cosmology; higgs inflaton; inflaton;

    Abstract : In this project a recent model of inflation in which the Standard Model Higgs field with a nonminimal coupling to gravity takes on the role of the inflaton field is investigated. The tensor to scalar ratio, spectral index and the running of the spectral index  is calculated for a tree level analysis and compared with the Planck experiment. READ MORE
