Spin-Dependent Antenna Splitting Functions
arXiv:0908.2450 · doi:10.1103/PhysRevD.81.054010
Abstract
We consider parton showers based on radiation from QCD dipoles or `antennae'. These showers are built from 2->3 parton splitting processes. The question then arises of what functions replace the Altarelli-Parisi splitting functions in this approach. We give a detailed answer to this question, applicable to antenna showers in which partons carry definite helicity, and to both initial- and final-state emissions.
