Abstract

We study differential intra-jet radiation patterns in jet production at full colour. We present a systematic study of several QCD 2→ 2 processes and also multi-jet production from a colourless initial state. We examine how subleading colour corrections are distributed differentially in phase space and find that mere normalization effects due to subleading colour can be due to subtle cancellations across phase space. In general, we find that subleading colour does affect the shapes of distributions.
