Advice for gluon vertex textbook

Click For Summary

Discussion Overview

The discussion revolves around deriving the three gluon vertex in Quantum Chromodynamics (QCD) using generating functionals. Participants seek references and guidance on the calculations involved, particularly in the context of path integrals and Green functions.

Discussion Character

  • Technical explanation
  • Homework-related
  • Debate/contested

Main Points Raised

  • One participant expresses difficulty in deriving the three gluon vertex and requests a step-by-step reference.
  • Another participant recommends Chapter 9 of Cheng & Li's "Gauge Theory of Elementary Particles" for a derivation using path integrals.
  • A different participant mentions having personal notes with calculations based on Bailin & Love's book, suggesting that explicit calculations may not be found in textbooks and encourages self-calculation of the vertex factor.
  • Another reference suggested is Muta's "Quantum Chromodynamics" as a standard text on the subject.

Areas of Agreement / Disagreement

Participants provide various references and approaches, indicating a lack of consensus on a single definitive source or method for deriving the three gluon vertex.

Contextual Notes

Some participants note that existing textbooks may not contain explicit calculations, and there is an emphasis on self-derived calculations based on theoretical principles.

Who May Find This Useful

Readers interested in QCD, particularly those looking for resources on gluon interactions and path integral formulations.

Hello everyone,
i'm having a hard time trying to derive the three gluon vertex in QCD, using the generating functional. Could someone please suggest a reference where it is computed step by step? My teacher lecture notes are not clear, and basically I don't understand what he's doing.
A very good reference on Green functions could be useful as well.
Thanks a lot!

I'd check out chapt. 9 of Cheng & Li -- Gauge Theory of Elementary Particles, where everything is derived using path integrals.
 
I have the calculation in my notes, which have text in Romanian. I don't think you have the explicit hand-made calculations in any book (my notes are built upon the brilliant book by Bailin & Love). You shouldn't look for a book to show the calculation, you can do it by yourself:

You read off the 3 vertex gluon factor once you put the 3-field term in the Lagrangian action from x to p representation with 4D Fourier transform. The 3-field expansion of int d^4 x F_a^{mu nu} F^{a}_{mu nu} you should calculate by yourself (it's gAApartialA), then trans-Fourier the product of 3 fields, then use the symmetry property (3 bosons).

Since this the is the book recommendation section, you can warmly use D.Bailin's and A.Love's "Introduction to Gauge Field Theory", IOP, 1993 for any QFT/Green functions questions.

A good standard text on QCD is Muta, Quantum Chromodynamics.
