Hadron operators on the light-cone

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

Meson and baryon operators on the light cone are studied which reproduce the well-known parton distribution amplitudes as matrix elements between the vacuum and an one-meson (baryon) state. We extent our previous results to the case of the quark-gluon mixing which is relevan for the description of a flavour-singlet meson. The anomalous dimensions of the considered nonlocal light-cone operators are calculated explicity in the one-loop approximation. We thus recover the evolution kernels for meson and baryon wave functions derived earlier by other authors using different methods.
