This project seeks to provide an introduction to some specific topics in Particle Physics, and prepare the student to join our graduate program with a project in this field. The proposal includes studies of scientific articles in particle physics and of specific articles related to hadronization. Also, it is expected that the student develop an analysis based on simulated events generated by a well known model used by the LHC experiments, PYTHIA. This event generator uses as the basis of its hadronization process the Lund model, that considers the evolution of color flux tubes, also known as strings. In addition to strings, the newer versions of PYTHIA include other mechanisms such as "Color Reconnection", "String Junctions" and "Color Ropes". We will study the effects caused by these mechanisms in the final experimental observables. Hence, during the year, the student will learn how to run the simulation, understand the different components of the event generator and develop analysis tools to study the outcome of the simulation. With this, he will gain knowledge on some basic concepts of particle physics, learn data analysis techniques and develop his programming skills. This project will be developed within the Hadrex Group (Física Hadrônica Experimental) of the Gleb Wataghin Physics Institute of the University of Campinas, and the student will be interacting directly and on a daily basis with the other students and researchers of this group. Hadrex group is a member of the ALICE collaboration, a Heavy Ion experiment of the LHC and this project is part of the FAPESP temático project "Hadronic Physics in High Energy Nuclear Collisions"(2017/05695-2).
