Would like some particle physics textbook-reading advice

Click For Summary

Discussion Overview

The discussion revolves around seeking advice on how to approach studying Quantum Field Theory (QFT) and particle physics in a limited timeframe. Participants share their thoughts on recommended resources and strategies for gaining a foundational understanding of these topics, considering the individual's background and upcoming lectures.

Discussion Character

  • Exploratory
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant expresses a need for guidance on which topics to focus on in "QFT and the Standard Model" by Schwartz, given their limited time and background in classical field theory and special relativity.
  • Another participant suggests that Schwartz's book may be too advanced for the individual's current level and recommends watching introductory lectures instead.
  • Some participants argue that QFT cannot be adequately understood in just two weeks and advise against rushing through the material, emphasizing the importance of appreciating the subject's depth.
  • Recommendations for alternative textbooks include "Modern Particle Physics" by Thomson and "Introduction to Elementary Particles" by Griffiths, which may be more suitable for beginners.
  • There is mention of available lectures and resources that could provide a more accessible introduction to particle physics without the need for extensive prior knowledge.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of learning QFT in a short period, with some advocating for a more gradual approach while others suggest focusing on introductory materials instead. No consensus is reached on the best method for studying within the given timeframe.

Contextual Notes

Participants note the individual's lack of knowledge in Group Theory, which may affect their ability to engage with the recommended texts and topics in QFT. There is also a recognition that the prerequisites for the upcoming lectures are minimal, which may influence the approach to studying particle physics.

Hi all,

I am in a bit of a funny situation where I need to pick up at least a cursory knowledge of QFT and particle physics in the space of two weeks. I borrowed "QFT and the Standard Model" by Schwartz but I have no idea how I should approach it. Ideally I'd pour through every page, but I definitely do not have the time to do so. Could someone suggest the topics (and their sequence) I should be focusing on? This is a link to the contents page: https://schwartzqft.fas.harvard.edu/

This is the current background I have: I know a little bit about classical field theory (Lagrangian/Lagrangian densities and whatnot) and special relativity from a course in Classical Electrodynamics. I also know a tiny bit of QFT/QED in the form of the quantisation of the EM field, however this was only a small part in a far-more-general course.

Also, I have no knowledge of Group Theory, so some advice regarding what I should read from this book (Intro to tensors and group theory for physicists): https://www.springer.com/us/book/9783319147932 would be nice as well!

Thanks in advance!

PS Basically I will be attending some lectures on particle physics in the summer holidays and after looking through the slides, I realized that I had absolutely no idea about what was going on. It's slightly worrying as I do wish to learn something from these lectures.

I've attached the slides to the introductory lecture: https://indico.cern.ch/event/709526/attachments/1670640/2686573/intro_pp_18.pdf

I think that Schwartz is overkill for this.

The Prerequisites link on

https://indico.cern.ch/event/709526/

states "No pre-requisites; this is an introductory overview."

Click on the Recording link at the URL I give above, and watch the whole lecture to see for yourself. No need to know about, e.g., SU(3) beforehand.

If you do want to look at some books, I recommend "Modern Particle Physics" by Thomson and/or "Introduction to Elementary Particles" by Griffiths.

QFT is not something that can be grasped in two weeks. Since your course prerequisites don't mention anything significant, I will advise you not to study QFT in a hurry. You'll not be able to sense the beauty in the subject if you storm through it.

Rather, go through a few talks which are on particle physics so that you know at least something. Here are a few:
