Abstract: Monte Carlo event generators, including their core parton shower component, are crucial for a wide range of physics applications at colliders. However the current "leading logarithmic" (LL) accuracy of parton showers is increasingly becoming a limiting factor in precision applications. This talk presents new "PanScales" dipole showers for hadron collisions, including the extension of the PanScales colour and spin-correlation schemes to initial-state branchings. The discussion will illustrate the physical characteristics of the showers that are required to achieve NLL accuracy. It will then demonstrate that the implementations of the new showers reproduce NLL accuracy, with explicit comparisons to all-order resummation results across a wide range of global and non-global observables in Drell-Yan and gluon-fusion Higgs production, including experimentally important observables such as the Drell-Yan and Higgs-boson transverse momentum distributions. To conclude, I will sketch the necessary ingredients to design an NLL accurate shower for deep-inelastic scattering, a key ingredient towards precise phenomenology at the Electron-Ion Collider.
