I come from an undeveloped country and I am currently near the end of my Bachelor's degree. Currently, I am seriously considering a career as a theoretical particle physicist. Therefore, I would like to apply to Masters programs that enhance my technical skills and enable me to develop required expertise in the following courses: Quantum Field Theory - all of Peskin and Schroder Group Theory - all of Georgi General Relativity - all of Hughston and Tod Supersymmetry - all of Wess and Bagger I believe that this is the foundational background to tackle cutting-edge research in string theory. What other subjects might you think I need to complete? The pre-PhD diploma at ICTP offers the advantage of offering just such a course.The program happens to offer such benefits without the baggage of courses such as graduate-level classical mechanics, electrodynamics, quantum mechanics and statistical mechanics. What's your opinion of the diploma program?
