High Energy Physics Notes
These notes are my effort to understand QFT. If you are anything like me, you find that you need to work out as much as possible in detail, including all the formula, before you really understand something. For me, it also helps a lot, if I write down everything explicitly.
This website has come online in December 2019 and is still very much WIP. I claim no originality or correctness whatsoever. If you have any comments, suggestions or feedback feel free to contact hep.notes@hotmail.com.
QFT Notes
These Notes are about my effort to understand QFT. This started by reading Peskin and Schroeder and so 90% of these notes are essentially working out details of that book. However, there are additions coming from Weinberg, Zee, Schwartz, Muta, Cheng and Lee, and even Carroll.

Update 11 November 2021
- Added a long overdue chapter on free field theory
- Added a chapter on the Minimal Supersymmetry Minimal Model
- Lots of typos correct and cosmetic changes
String Theory Notes
The approach to these notes, is different from the QFT Notes. Here I just comment on Polchinski’s String Theory book, deriving most of the formula in detail, or adding context, where I feel it is useful to me. I have just started, this, so bear with me on this one.
It has taken me a while to finish chapter 8, but it is a lengthy and difficult one; my notes are over 150 pages for that chapter alone. I still have many open questions which I have added at the start of each respective chapter.
I will now take a short break before I delve into chapter 9.

General Relativity & Cosmology Notes
These notes provide my personal road to understanding general relativity and the beginnings of cosmology. There are fortunately several excellent text books and lecture notes on the subjects, so I cannot not claim any originality to my approach. https://hepnotes.files.wordpress.com/2023/01/general-file-1.pdf
