Abstract

With many applications in high-energy physics, Deep Learning or Deep Neural Network (DNN) has become noticeable and practical in recent years. In this article, a new technique is presented for modeling the charged particles multiplicity distribution Pn of Proton-Proton (PP) collisions using an efficient DNN model. The charged particles multiplicity n, the total center of mass energy s, and the pseudorapidity η used as input in DNN model and the desired output is Pn. DNN was trained to build a function, which studies the relationship between Pn n,s,η. The DNN model showed a high degree of consistency in matching the data distributions. The DNN model is used to predict with Pn not included in the training set. The expected Pn had effectively merged the experimental data and the values expected indicate a strong agreement with Large Hadron Collider (LHC) for ATLAS measurement at s = 0.9, 7 and 8 TeV.
