标题： Perturbative QCD description of multiparticle correlations in quark and gluon jets

摘要： 在夸克和胶子喷注中多重性分布的因子矩的修正领先对数近似下的QCD演化方程，通过充分考虑能量守恒定律，在阈值处的初始条件下来数值求解。 在应用局部部分子-强子对偶性作为强子化方案后，实现了对可用实验数据的定量一致描述，包括任意阶的因子累积量和因子矩及其比值，在夸克和胶子喷注以及$e^+e^-$湮灭中的情况。 显示英文摘要

摘要： The QCD evolution equations in Modified Leading Log Approximation for the factorial moments of the multiplicity distribution in quark and gluon jets are numerically solved with initial conditions at threshold by fully taking into account the energy conservation law. After applying Local Parton Hadron Duality as hadronization prescription, a consistent quantitative description of available experimental data for factorial cumulants and factorial moments of arbitrary order and for their ratio both in quark and gluon jets and in $e^+e^-$ annihilation is achieved.
