(Check here frequently for important announcements related to the course)
Class location/time: Mondays and Wednesdays, 11.00 am. to 12.15 pm., via zoom (link given in email sent to all students registered: it is also listed in ELMS under the zoom tab)
Instructor: Kaustubh Agashe, Rm. 3118, Physics Sciences Complex; Phone: (301) 405-6018; E-mail:

Goal of course:
This course will develop the theory of the Standard Model of particle physics (and if time
permits, one of its extensions).
Who should take this course: The target audience is graduate students who wish to do
research in the broad area of theoretical particle physics, including cosmology/gravity and nuclear physics.
It might also be useful for those planning to work on related experiments.
Background: (required) introductory course on quantum field theory (QFT) (for example, Phys 624)
and (recommended) a course on ``phenomenology’’ (or survey) of SM (for example, Phys751) .
Required: A First Book of Quantum Field Theory, by Amitabh Lahiri and Palash B. Pal
The following are recommended:
An Introduction to Quantum Field Theory, by Michael E. Peskin and Daniel V. Schroeder
Quantum Field Theory by F. Mandl and G. Shaw
Gauge Theory of Elementary Particle Physics by Ta-Pei Cheng and Ling-Fong Li
Weak Interactions and Modern Particle Theory, Howard Georgi (also online here)
(The above textbooks are useful for learning the theory of the SM.)
Dynamics of the Standard Model by John F. Donoghue, Eugene Golowich and Barry R. Holstein
(The last textbook is more about the phenomenology of the SM, although it has a nice
summary of the theory of the SM in the beginning chapters.)
The course grade will be based on homeworks (75%) assigned here on
a bi-weekly basis (roughly) and a term paper, including its presentation during
finals week (25%) (some suggestions for topics for term paper are posted here: dates
of presentation will be decided later).
All work should be submitted online (via ELMS here, navigate to Phys752 course, then "Assignments").
The parts I and II will roughly follow Chapters 12 through 15 of A First Book of Quantum
Field Theory, by Lahiri and Pal, suitably supplemented by material from other books
Part I: QFT topics
Renormalization in Quantum Electrodynamics (QED); Renormalizable theory for massive
Gauge bosons (i.e.,Spontaneous Symmetry Breaking and Higgs mechanism); Non-abelian (gauge)
Theories (including possibly their quantization)
Part II: Theory (and resulting phenomenology) of SM
Particle content and gauge symmetries; Higgs mechanism and “bottomline” interactions; Specific
Part III: Beyond the SM
Time permitting, we will discuss one of the extensions of the SM, either extra dimensions
(typed-up notes for which are provided here) or grand unified theories (roughly
following chapter of Gauge Theory of Elementary Particle Physics by Cheng and
Topics such as “anomalies” and other extensions of the SM (such as supersymmetry) might be covered
in more advanced courses such as PHYS 851 (being offered this semester).
