    • New tools to constrain EFTs and CFTs 

      Zahed, Ahmadullah
      In this thesis, we develop new methods for the S matrix bootstrap in the context of 2-2 scattering amplitudes and four-point correlators in conformal field theories (CFTs). For 2-2 scattering in quantum field theories, ...

    • On Hypergeometric solutions of Feynman integrals using Mellin-Barnes Integrals with Applications 

      Banik, Sumit
      Experimental measurements of physical observables in particle colliders rely on high-precision theoretical calculations to validate the predictions of any theoretical model and detect signals of new physics. These theoretical ...

    • Phenomenological Explorations in Dark Matter 

      Chatterjee, Shiuli
      The previous decade has seen an explosive increase in explorations into the nature of dark matter (DM) encompassing astrophysical, particle and cosmological probes. We face today a large body of gravitational evidences ...
