    • Coherent states and classical radiative observables in the S-matrix formalism 

      Gonzo, Riccardo (Trinity College Dublin. School of Mathematics. Discipline of Pure & Applied Mathematics, 2022)
      In this thesis, we study classical radiative observables perturbatively in terms of on-shell scattering amplitudes. In particular, we focus primarily on the two-body problem in gauge and gravitational theories by using an ...

    • Hadron Scattering Amplitudes from Lattice QCD 

      Lang, Nicolas (Trinity College Dublin. School of Mathematics. Discipline of Pure & Applied Mathematics, 2023)
      In this thesis we compute hadron scattering amplitudes within the framework of lattice quantum chromodynamics. Finite-volume spectra are computed using distillation and the variational method. These spectra constrain ...
