SUMMARY:Analytic QCD ingredients for NNLL resummation and parton showers
DESCRIPTION:Mrinal Dasgupta (Manchester) \nWe discuss QCD calculations for specific analytic ingredients necessary to construct high logarithmic accuracy (NNLL) parton showers. \nIn particular we show how to extend the notion of a physical coupling defined in the soft limit into the collinear region. This extension allows for the incorporation of the resummation coefficient known as B2 into a parton shower in an observable independent manner. \nCombined with other key developments we mention\, our results allow parton showers to achieve NNLL accuracy for a wide class of observables.
