Within the picture of Local Parton Hadron Duality, the perturbative QCD predictions can successfully describe the available experimental data.LaTeX, 3 pages, to appear in Proc. of XXXIIIrd Rencontres de Moriond, `QCD and high energy interactions'', Les Arcs, France, March 21-28, 1998High Energy Physics - Phenomenologytext
