Charged particle fluctuations using factorial moments at LHC energies

Phase transition and critical point is a subject of great importance in many fields, however in the field of heavy ion collisions, we are still unaware about the nature of the quark-hadron phase transition and vice-versa. Phase transitions (PT) are usually possible only in systems with interactions among its constituents and it is well known that the behavior of the system near a phase transition point shows critical phenomena and exhibit fluctuations due to tension between ordered (collective) and the disordered (thermal) dynamics. One of the measures to learn about the dynamics of heavy ion collisions is to study scaling properties of multiplicity fluctuations over wide range of bin sizes by studying the spatial patterns in the events
