The number of charged particles inside jets is a widely used discriminant for identifying the quark or gluon nature of the initiating parton and is sensitive to both the perturbative and non-perturbative components of fragmentation. This paper presents a measurement of the average number of charged particles with inside high-momentum jets in dijet events using 20.3 fb of data recorded with the ATLAS detector in pp collisions at collisions at the LHC. The jets considered have transverse momenta from 50 up to and beyond 1.5 . The reconstructed charged-particle track multiplicity distribution is unfolded to remove distortions from detector effects and the resulting charged-particle multiplicity is compared to several models. Furthermore, quark and gluon jet fractions are used to extract the average charged-particle multiplicity for quark and gluon jets separately.

“…Experimentally, the transition between hard and soft processes is determined by the identification of jets through some jet-finding processes, e.g. Jade [1] or Durham [2] algorithm. In these processes there is a parameter -y cut , which, in case of Durham algorithm, is essentially the relative transverse momentum k t squared [3],…”

A study of the dynamical fluctuation property of jets is carried out using Monte Carlo method. The results suggest that, unlike the average properties of the hadronic system inside jets, the anisotropy of dynamical fluctuations in these systems changes abruptly with the variation of the cut parameter y cut . A transition point exists, where the dynamical fluctuations in the hadronic system inside jet behave like those in soft hadronic collisions, i.e. being circular in the transverse plan with repect to dynamical fluctuations. This finding obtained from Jetset and Herwig Monte Carlo is encouraged to be checked by experiments.PACS number: 13.85 Hd
