Spinor dotted and undotted indices
I have had an introduction to QFT following the book of Mandl and Shaw. However, I have been asked to write a report on the CPT theorem. For this, the main reference I'm using is PCT, spin and ...

Index Placement for Spinors in Relativity
This may ultimately be a silly question, but a pedantic mind like mine gets tied into knots over differing notation. (Disclaimer: I'm a mathematician.)
Let $\mathbb{W}$ be a complex two-dimensional ...
