QFT: groups, effective action, fiber bundles, anomalies, EFT

Click For Summary
SUMMARY

The forum discussion centers on advanced topics in Quantum Field Theory (QFT), specifically seeking textbooks and resources. Key areas of interest include the Lorentz group and Lie group representations, effective action and potential, gauge fields, anomalies, and topological aspects of quantum theory. Recommended texts include S. Weinberg's "The Quantum Theory of Fields" and several works on finite-temperature QFT, such as M. LeBellac's "Thermal Field Theory" and J. I. Kapusta's "Finite-Temperature Field Theory." The discussion also highlights the need for resources that approach QFT from a mathematical perspective.

PREREQUISITES
  • Understanding of Quantum Field Theory (QFT) fundamentals
  • Familiarity with group theory, specifically Lorentz and Lie groups
  • Knowledge of gauge theory and its geometric interpretations
  • Basic concepts of anomalies in quantum theories
NEXT STEPS
  • Research "Quantum Field Theory: A Modern Primer" by Michael Peskin and Daniel Schroeder
  • Study "Thermal Field Theory" by M. LeBellac for insights on finite-temperature QFT
  • Explore "An Introduction to Quantum Field Theory" by Michael Peskin for a comprehensive overview
  • Investigate mathematical approaches to QFT, such as "Quantum Field Theory in a Nutshell" by Anthony Zee
USEFUL FOR

Physicists, graduate students in theoretical physics, and researchers focusing on Quantum Field Theory, particularly those interested in advanced topics like anomalies, gauge fields, and mathematical frameworks in QFT.

Hi, I am looking for textbooks in QFT. I studied QFT using Peskin And Schroeder + two year master's degree QFT programme.
I want to know about the next items:
1) Lorentz group and Lie group (precise adjectives, group representation and connection between fields and spins from the standpoint of Lorentz group)
2) Effective action, effective potential, external sources.
3) Geometric sense of gauge fields (Vertical and horizontal bundles, connection with tensors)
4) Anomalies
- clear division between axial anomaly in QCD (Theta Vacuum: axion -> 2 gluons) and axial anomaly in QCD of current (Chern–Simons term: pion->two photons, photon->three pions, ...)
- consideration anomalies in different approaches (perturbative, functional, topological (index theorem))
- difference between Consistent, Covariant, Multiplicative Anomalies
5) topologically aspects of quantum theory (instantons, sfalerons, Theta Vacuum)
6) effective theory field (sigma models, Nambu–Jona-Lasinio model)
7) introduction temperate in theory.

I would appreciate for good books.

I don't underst and 7). Do you mean finite-temperature QFT? Then I'd recommend

M. LeBellac, Thermal Field Theory, Cambridge University Press, Cambridge, New York, Melbourne, 1996.
J. I. Kapusta and C. Gale, Finite-Temperature Field Theory; Principles and Applications, Cambridge University Press, 2 ed., 2006.
M. Laine and A. Vuorinen, Basics of Thermal Field Theory, vol. 925 of Lecture Notes in Physics, 2016.

Yes. Thank you for advice. Is there something other than Weinberg?

And I would like to know are there any QFT books written from a mathematical view?
