Quantum Field Theory: Scans of Lecture Notes

Most lectures — regular or extra — for the QFT classes are mirrored on Zoom and recorded on the cloud, with the records available on Canvas. Unfortunately, due to techical glitches some lectures do not get recorded. For these un-recorded lectures, I am going to scan my notes, post them on my web site, and link them to this page, see below.

Fall 2024 semester

Regular lecture #1 on August 26:

That class did not get recorded at all.
Fortunately, I used pre-made notes for the whole lecture:
Part 1: Syllabus and administration of the class.
Part 2: Reasons for QFT, field-particle duality.
Part 3: Intro to classical field theory: Lagrangian mechanics; classical fields; examples of field equations.

Regular lecture #14 on October 14:

The lecture is recorded and published on Canvas, but there was a lot of new material, and the students asked for the scanned notes. Here they are.

Spring 2025 semester

Extra lecture #2 on January 31:

This second lecture on Grand Unified Theories did not get recorded; sorry.
Here are scans of my lecture notes.

Extra lecture #5 on March 28:

The lecture on Lattice Gauge Theories did not get recorded or the record was lost; sorry.
Here are scans of my lecture notes.

Regular lecture #20 on March 31 :

The lecture was not recorded or the record was lost.
Fortunately, I used pre-made notes for the whole lecture:
Part 1: BRST symmetry.
Part 2: renormalizability of QCD and other guage theories.
Part 3: QCD beta function, start of the calculation.

Extra lecture #7 on April 25:

The lecture on Green–Schwarz mechanism did not get recorded or the record was lost; sorry.
Here are scans of my lecture notes.
