Suggestions for sources with detailed calculations in quantum field theory.

Click For Summary

Discussion Overview

The discussion revolves around the search for online resources that provide detailed calculations in classical and quantum field theory (QFT), particularly for self-learners who may not have access to teachers or peers for assistance. Participants express the challenges faced when textbooks do not include all intermediate steps in calculations.

Discussion Character

  • Exploratory, Homework-related

Main Points Raised

  • One participant requests suggestions for online resources that include detailed calculations in classical or quantum field theory, noting that many textbooks assume guidance from teachers.
  • Another participant questions the original poster's mathematical and physical background, suggesting that most students should be able to perform calculations independently and recommending Halzen & Martin's "Quarks and Leptons" for its explicit calculations.
  • A third participant agrees that while average students should manage calculations, some may require additional assistance, mentioning standard QFT books like Peskin and Schroeder.
  • A fourth participant suggests accessing Srednicki's book for free and looking for a solutions manual to aid in understanding calculations.

Areas of Agreement / Disagreement

Participants express a mix of views on the necessity of detailed calculations in QFT resources. While some believe that students should be able to handle calculations independently, others acknowledge that initial assistance may be beneficial. No consensus is reached on the best resources available.

Contextual Notes

Participants do not specify the prerequisites for understanding QFT or the particular types of calculations they find challenging, leaving some assumptions about the audience's background and needs unaddressed.

Who May Find This Useful

Students and self-learners in physics, particularly those studying classical or quantum field theory, may find this discussion relevant as they seek resources for detailed calculations.

Can you suggest any source available on internet which may be particularly helpful for those studying/brushing up knowledge of classical or quantum field theory without help of any teacher or friend? Some calculations are at first not so straightforward and there are many types of calculations requiring special tricks and caution to get the correct answer. Most books do not show all the intermediate steps of calculations perhaps because such books are meant to be used under guidence of teachers who are supposed to help the students by showing detailed steps in the classroom. But those with practically no such help face difficulty. Is there any help on internet for such students?

What is your mathematical/physical background? Are you sure to be enough prepared for QFT? The point is that usually most books don't perform explicit calculation because they are often rather long and an average student can do it by himself.
However, according to my experience a very good book with an accettable number of explicit calculations is Halzen & Martin - "Quarks and Leptons". It is quite explicit in the first part, when you need it to be.
 
I agree that an average student should be able to do the calculations but perhaps at initial stage he or she may need some assistance. (At least someone like me would need.) I would consider standard qft books at the level of Peskin and Schroeder.
 
You can get Srednicki's book for free, and try to find the solutions manual somewhere
