摘要
The controversy in experimental data on the transverse momentum dependence of intermittency at different energies is studied.It is shown that this controversy is due to the appearance of a new component-the jet(or mini-jet)component together with the normal soft one at the collider energies.It is shown that the compensation effect of these two components results in a U shape for the dependence of intermittency indices on the average transverse momentum per event P_(⊥)which is a good quantity to characterize the relative size of soft and hard components in an event.In a linearization approximation the fraction of the soft component can be determined directly from P_(⊥).
