"Recommendations\n\nTo have passed an introductory course in particle and nuclear physics, as the one in the bachelor’s degree in Physics at the UB.\n\nTo have been exposed to an introductory course of high energy physics and accelerators, as the one in the bachelor’s degree in Physics at the UB.\n\n \n\n \n\nLearning objectives\n\n \n\nReferring to knowledge\n\nThis subject is an introduction to modern elementary particle physics.\nThe course is an overview of the field. It starts with the basic taxonomy of particle physics. The role of conservation rules and symmetries is discussed. The basics of field theory required for the quantification of relativistic processes is introduced. The three well established gauge theories (QED, QCD and electroweak interactions) are described and the basic techniques to evaluate cross sections and decay rates for some processes at first order are given.\n\n \n\n \n\nTeaching blocks\n\n \n\n1.

"The master's degree Astrophysics, Particle Physics and Cosmology of the University of Barcelona is intended for holders of bachelor's degrees and equivalent undergraduate degrees (particularly in physics), engineers and technical engineers who wish to pursue a specialization in one of the following branches of knowledge: astrophysics and space sciences; atomic, nuclear and particle physics; or gravitation and cosmology. The duration and specific content will depend on each applicant's previous studies.\nThe master's degree seeks to provide students with the training needed to conduct research in one of the fields listed above or in a related field, thanks to the interdisciplinary subjects also included in the program.\n\nThe course focuses on preparing students to begin a doctoral thesis upon completion of their degree, enabling them to pursue an academic career. However, it also provides highly valuable training for a career in the public or private sector, opening up a wide range of employment options.\n\nObjectives\nThe objectives of the master's degree are to provide students with advanced academic training in the fields of astrophysics, space sciences, atomic, nuclear and particle physics, gravitation and cosmology. More specifically, the objectives are:\n\n\n\nto study the content of a carefully selected set of subjects;\n\nto acquire the work methodology needed for conducting research and completing a doctoral thesis in the above fields through the completion of one or more research projects during the program;\n\nto acquire the skills needed to give scientific presentations;\n\nto acquire the competences, skills and abilities required to join a research group and complete doctoral studies or eventually join companies that pursue developments related to research in the mentioned fields.\n\nCompetences\nThe generic competences obtained by students will be instrumental (such as the capacity for analysis and synthesis, a working knowledge of English, knowledge of software tools and decision-making skills), interpersonal (such as critical reasoning, teamwork and creativity), and systemic (such as the capacity for independent learning and the capacity to adapt to new situations).\n\nThe specific competences obtained by students will be the capacity to understand a physical system in terms of the relevant scales of energy, the capacity to identify observable magnitudes and the capacity to test predictions from theoretical models with experimental and observational data.\n\nAnother potential specific competence is the capacity to develop and apply new technologies."@en . . .
