• Matching between supersymmetric effective theory of inflation and pure de Sitter SUGRA 

      Serrano Morales, Federico
      Several models of inflationary cosmology have been recently established. They provide a wide and rich field of research where most of the predictions are meant to be tested within the next generation of cosmological ...
    • On-shell methods in QCD and for WBF Higgs 

      Torres Bobadilla, William Javier
      Se estudian técnicas recursivas para calcular de forma eficiente amplitudes de scattering a nivel perturbativo en teorías gauge, en particular procesos a tree-level y one-loop en la teoría QCD. Usando el formalismo de ...

    • Scattering equations formalism for QCD and supersymmetric Yang-Mills theories 

      Vesga Simmons, Juan Pablo
      Scattering amplitudes are one of the most important observables in perturbative quantum field theory, because they allow for the calculation of cross-sections, which are central to collision experiments. In this thesis, ...

    • Short distance constraints from HLbL contribution to the muon anomalous magnetic moment 

      Melo Porras, Daniel Gerardo
      Hadronic Light by Light (HLbL) scattering is not the biggest hadronic contribution to the muon’s anomalous magnetic moment, but it has the biggest relative uncertainty of all the contributions to that observable. With the ...
