dc.descriptionOne of the key ideas in describing the multiparticle production at high energies in the perturbative QCD is the angular ordering in successive soft-gluon emission. We analyse the angular distribution of particles in a jet, and investigate the corrections to the angular ordering. At a small angle from the jet direction, the angular ordering is exact at the next-to-leading order. At a large angle, the angular ordering overestimates the angular particle density by a factor $(1-γ\ln \cos^2(θ/2))$, where $γ$ is the anomalous dimension of the multiplicity. The $O(γ)$ correction restores the boost invariance of the cross section.
