I Recommendations for learning renormalization?

[RobertGC]

TL;DR

Texts for a gentle intro to quantum field theory.

I’ve tried multiple times to learn the methods of renormalization without success. Assume I know quantum mechanics at the level of Griffith’s, Introduction to Quantum Mechanics what’s a good intro to learning renormalization?

what’s a good intro to learning renormalization?

There isn't one. You can't skip past the beginning of QFT into the middle.

Ok. What’s a good intro to QFT?

There are two series of lectures on YouTube by Tobias Osborne:



Another option, if you consider yourself sufficiently gifted is:

You can learn renormalization in quantum mechanics as a prelude for its later use in quantum field theory. Most of the mystery of the renormalization process will be gone after having read my paper

• Arnold Neumaier, Renormalization without infinities – an elementary tutorial, 2015.

But nothing can save you from going through the long calculations accompanying the applications in quantum field theory.

Thanks. I’ll give those a look.

Have you tried Klauber, Student Friendly QFT?

 

[vanhees71]

My favorite intro text is

M. D. Schwartz, Quantum field theory and the Standard Model, Cambridge University Press, Cambridge, New York (2014).

Especially for renormalization there is

J. C. Collins, Renormalization, Cambridge University Press, Cambridge, New York, Melbourne (1986).

Here you find my notes on QFT including renormalization using both the dimensional-regularization and the direct BPHZ approach (without intermediate regularization):

Thanks for the ref.

I'd also recommend reading through the first seven chapters of Peskin and Schroder carefully.

Peter Weisz's 2009 Les Houches notes are a nice intro to Collins. Although Collins itself is very well written.

The emphasis is on "carefully". A textbook, where dimensionful arguments of logarithms occur in the chapter on renormalization, must indeed be read with great care. It's really a pitty that this in principle very good textbook is so full of non-trivial typos :-(.

My website moved. Change in all my old links arnold-neumaier.at to arnold-neumaier.at and you'll find the corresponding files.

Thanks a lot Prof. Neumaier!

Actually the change announced first was invalid; see the corrected version.

I suggest starting with Halzen and Martin.
