Logarithmic accuracy of angular-ordered parton showers

Logarithmic accuracy of angular-ordered parton showers

Abstract We study the logarithmic accuracy of angular-ordered parton showers by considering the singular limits of multiple emission matrix elements. This allows us to consider different choices for the evolution variable and propose a new choice which has both the correct logarithmic behaviour and...
