Resummation and Simulation of Soft Gluon Effects beyond Leading Color
Matthew De Angelis, J. R. Forshaw, Simon Plätzer
Abstract
We present first results of resumming soft gluon effects in a simulation of high-energy collisions beyond the leading-color approximation. We work to all orders in QCD perturbation theory using a new parton branching algorithm. This amplitude evolution algorithm resembles a parton shower that is able to systematically include color-suppressed terms. We find that color-suppressed terms can significantly contribute to jet veto cross sections.
