The charged particle multiplicity is one of the simplest observable in collision of the hadrons, imposing constrains on the mechanisms of the particle production. Multiplicity distributions at lower energies have been studied earlier. In this work, it has been investigated how the multiplicity distributions and fluctuations have been explained in LHC energies. For this, a detailed study has been done from √s=7.7 GeV/A to √s= 2.76 TeV/A with event generators AMPT-Default and AMPT-String Melting. It will be also discussed how multiplicity distribution parameters are related to early stages of collision and how small-x helps to find information on initial states.
