QCD and experiment on multiplicity distributions
I. M. Dremin
Abstract
The solution of QCD equations for generating functions of parton multiplicity distributions reveals new peculiar features of cumulant moments oscillating as functions of their rank. It happens that experimental data on hadron multiplicity distributions in e+e-, hh, AA collisions possess the similar features. However, the "more regular" models like λϕ3 behave in a different way. Evolution of the moments at smaller phase space bins and zeros of the truncated generating functions are briefly discussed.
