Parton showering with higher-logarithmic accuracy for soft emissions
Silvia Ferrario Ravasio, Keith Hamilton, Alexander Karlberg +3
The accuracy of parton-shower simulations is often a limiting factor in the interpretation of data from high-energy colliders. We present the first formulation of parton showers wi…
