It has been shown recently that additional information can be ob- tained from charged particle multiplicity distribution by investigating their mod- ified combinants C j, which exhibit periodic oscillatory behaviour. The modified combinants obtained from experimental data can be expressed in a recurrent form involving the probability of obtaining N charged particles P(N), scaled by the void probability P(0). The effects of various experimental observables such as |η|, pT and centre-of-mass collision energy √s on the oscillations of C j will be discussed.
