Abstract: This paper studies the multiplicity distribution of hadrons produced in p-p collisions at 0.9 and 2.36 TeV using ALICE as a detector. The multiplicity distribution exhibits enhanced void probability. They are also found to satisfy the void probability scaling. The scaling of χ with n̄κ̄ 2 is studied using the generalized hypergeometric model. The variation of the parameter "a" of the hyper geometric model with energy and type of events is also studied. The parameter "a" distinguishes between various theoretical models, e.g. Lorentz/Catalan, negative binomial, geometric distribution etc. Finally a comparison is made with the p - p̄ collisions at 200, 546 and 900 GeV. It is observed both for p-p and p - p̄ data, the value of "a" decreases with increase in collision energy and approach towards the upper bound or the NB model of the void probability scaling. © 2012 World Scientific Publishing Company.
