Phenomenological and cosmological implications of classically scale-invariant standard model extensions (Doctoral thesis)

Καράμ, Αλέξανδρος


n this thesis, we investigate the phenomenology and cosmological consequences of classically scale-invariant Standard Model extensions. We explore how models with classical scale invariance, where all mass scales are dynamically generated, can address various contemporary high-energy physics problems without destabilizing the Higgs mass. The vacuum stability, dark matter and neutrino mass problems are simultaneously addressed in an SU(2)X extension. We also explore an SU(3)X extension due to its rich phenomenology regarding dark matter. Finally, we address the dynamical generation of the Planck scale in conjunction with the theory of cosmic inflation and study various aspects pertaining to the inflationary observables.
