P622 Relativistic Quantum Field Theory II (Not offered in 2008, Offered Spring 2009)

This class is a continuation of P621.  The text is “An Introduction to Quantum Field Theory” by M. E. Peskin and D. V. Schroeder.  We will cover many topics from the following chapters of Peskin & Schroeder:  7, 8, 9, 10, 12, 14, 15, 16 and 17.   Note:  in general we will not cover the advanced topics that are marked with an  *  in the table of contents of Peskin & Schroeder.

I.    Radiative Corrections

II.    Renormalization
        A)    Functional Methods
        B)    Systematics of Renormalization
        C)    Renormalization Group

III.    Non-Abelian Guage Theories   
        A)    Non-Abelian Guage Invariance
        B)    Quantization of Non-Abelian Theories
        C)    QCD
