Instructor: Prof.Yamamoto, Prof. Hazumi

Description of the course:

This course is made of two parts: first part is a lecture-based course on the theoretical background of C, P, and T symmetries, and the second part is an intensive lecture series on the exprimental aspects by Prof. Hazumi of the High Energy Accelerator Organization (KEK).

1st part: Starting from intuuitive definitions of C, P, and T transformations, we construct the theoretical framework of C, P, and T symmetries in Quantum Field Theory leading to a proff of the CPT theorem. Also covered are various selection rules and the Kobayashi-Masukawa mechanism of CP violation in the standard model. Very basic knowledge of quantum field theory is required, but we will briefly review it at the beginning of the class.

2nd part: to be announced later.

Announcements

(Mr. Miura or Ms. Endo)

Regular class is Wednesday 10:30am in room 7008 (new building)

Special lectures by Prof. Hazumi will be held 9/2-4, 2003

Title: "Measurement of CP Violation"

Abstract

CP violation is one of the most intriguing phenomena in elementary particle physics today. After deriving key formulas to understand the essence of CP violation in the kaon system and the B-meson system, we review the principles of ALL the experiments in which CP violation was observed, so as to provide a comprehensive understanding on what have experimentally been established. We then turn to the matter-antimatter asymmetry of the universe and review related astrophysical observations. We point out that CP violation in the standard model of elementary particles is too small to explain the creation of the matter-dominant universe, and some breakthrough is needed to solve this problem. In the end, we briefly discuss new ideas to explore CP violation beyond the standard model.

In addition, there will be a 90 min seminar.

Lectures

Lecture notes are posted here. Print them out and bring the relevant section to the class.

Some tips:

• try to focus on lecture and lecture notes rather than taking notes of everything.
• never think that your questions may be too trivial.; chance is that by asking seemingly simple questions, you are doing great favor for others who are too afraid to ask. Active participation in class is an inportant part of the grading scheme.

Grading scheme

Grades are based on the amount of active participation during the class and a final exam which is a take home report.
