 Parton showers are essential tools for predicting QCD physics at colliders across a wide range of momenta from the TeV down to the GeV regime. In the presence of such disparate momenta, the perturbative expansions of quantum field theories have coefficients enhanced by large logarithms of the ratios of momentum scales. One way of viewing parton showers is as automated and immensely flexible tools for resumming those logarithms, thus correctly reproducing the corresponding physics. Higher logarithmic accuracy for parton showers should make them considerably more powerful tools for analysing and interpreting experimental data at CERN’s Large Hadron Collider and potential future colliders. In this talk, I will review major breakthroughs in advancing the logarithmic accuracy of parton showers in recent years. I will mainly focus on how to build a dictionary between parton shower simulation and logarithmic resummation and discuss potential implications for phenomenology.
