Contribution of various processes to charm quark production in p+p collisions at different energies

Abstract

There are six types of quarks and on the basis of mass variation we catagories them into light flavors and heavy flavors. We study charm quark in this thesis. We study the three different production mechanisms Flavor Creation, Flavor Excitation and Gluon Splitting which are Leading Order(LO) and Next to Leading Order(NLO). To understand the variation in contribution we consider three center of mass energies that are √ s = 200 GeV, √ s = 2.76 TeV and √ s = 14 TeV. The contribution also effects the total cross section. We try to reproduce the experimental measurement from the theoretical understanding. We use Monte-Carlo LO based event generator that is PYTHIA8. It works on C++ programming language.
