    • Aspects of Scattering Amplitudes and Moduli Space Localization 

      Mizera, Sebastian (University of Waterloo, 2019-08-19)
      We propose that intersection numbers of certain cohomology classes on the moduli space of genus-zero Riemann surfaces with $n$ punctures, $\mathcal{M}_{0,n}$, compute tree-level scattering amplitudes in quantum field ...
    • Assessing the Accuracy of Cosmological Parameters Estimated from Velocity – Density Comparisons 

      Hollinger, Amber (University of Waterloo, 2024-01-10)
