 Title: MODIFIED PARTON BRANCHING MODEL FOR MULTI-PARTICLE PRODUCTION IN HADRONIC COLLISIONS - APPLICATION TO SUSY PARTICLE BRANCHING Authors: ZHANG YUANYUAN Keywords: particle physics, phenomenology, supersymmetric particle branching, multiplicity distribution, stochastic branching equation, hypergeometric function Issue Date: 10-May-2016 Abstract: The stochastic branching model of multi-particle productions in high energy collision has theoretical basis in perturbative QCD, and also successfully describes the experimental data for a wide energy range. However, over the years, little attention has been put on the branching model for supersymmetric (SUSY) particles. In this thesis, a stochastic branching model has been built to describe the pure supersymmetric particle jets evolution. This model is a modified two-phase stochastic branching process, or more precisely a two phase Simple Birth Process plus Poisson Process. The general case that the jets contain both ordinary particle jets and supersymmetric particle jets has also been investigated. We get the multiplicity distribution of the general case, which contains a Hypergeometric function in its expression. We apply this new multiplicity distribution to the current experimental data of $pp$ collision at center of mass energy $\sqrt{s} = 0.9, 2.36, 7 ~\textup{TeV}$. The fitting shows the supersymmetric particles haven't participate branching at current collision energy URI: http://scholarbank.nus.edu.sg/handle/10635/126077 Appears in Collections: Master's Theses (Open)
