Critical Angle in the Parton Cascade
arXiv:hep-ph/9511457 · doi:10.1007/BF02909153
Abstract
The angular correlation function of partons in a jet, as derived from perturbative QCD, is nonanalytic at a critical angle which separates a multiparticle regime with scaling properties from a regime with few particles near the hadronisation scale. Some phenomenological consequences are discussed.
