摘要
摘要本文的研究表明:QCD能够描述强子在非常高能量下相互作用的主要性质，包括总非弹性和衍射截面的行为。次级强子的包络谱是由具有横向动量qt ~ qo的胶子微射流的产生和破碎所控制的，其能量增长为q2 t ~ q 2o ~ A2exp(2.5√lns)。由于这个事实，人们可以应用pert。QCD来讨论通常被认为是“软”的过程。
Abstract It is shown that pert. QCD is able to describe the main properties of the hadron interactions at very high energies, including the behaviour of the total inelastic and diffractive cross sections. The inclusive spectra of secondary hadrons are governed by the production and fragmentation of the gluon minijets with transverse momentum qt∼qo , which grows with energy as q2 t ∼q 2 o∼ A2exp(2.5√lns). Thanks to this fact one can apply the pert. QCD to discuss the processes, which are usually considered to be “soft”.
