    Abstract : Weak-scale supersymmetry is one of the most favoured theories beyond the Standard Model of particle physics that elegantly solves various theoretical and observational problems in both particle physics and cosmology. In this thesis, I describe the theoretical foundations of supersymmetry, issues that it can address and concrete supersymmetric models that are widely used in phenomenological studies. READ MORE

  3. 3. The Extremes of Neutrino Astronomy From Fermi Bubbles with IceCube to Ice Studies with ARIANNA

    University dissertation from Uppsala : Acta Universitatis Upsaliensis
