摘要：

We discuss implications of perturbative QCD for the structure of jets in e+e- annihilation above 10 GeV c.m. energy. (i) A strong asymmetry in the transverse momentum distribution in e+e- → 2 jets originates from lowest order gluon bremsstrahlung; one jet broadens and the other does not. (ii) Since the gluon is flavor neutral, quantum number correlations between the hadrons in the two jets are smaller than predicted by the parton model. (iii) Jet distributions in QCD are compared with scalar gluon theories. (iv) Three-jet structure begins to emerge around 10-15 GeV c.m. energy. It should be clearly visible in low-thrust or high-sphericity data at Ec.m. = 30 GeV. © 1979.
