Bhabha Scattering With The Spinor Helicity Formalism | Quantum Field Theory

In this video, I use the spinor helicity formalism to perform a calculation that I have already done in another video (the calculation of the ultra-relativistic Bhabha differential scattering cross section), for practice and comparison.
Here is my previous video on Bhabha scattering:
• Bhabha Differential Sc...
Note: the bosonic normalization I chose to use in the general differential scattering cross section is not arbitrary, apart from not including mass factors. It is the one consistent with the usual spinor-helicity formalism.

Blessed to have found your videos!

I commend u so much for understanding this stuff and then sharing that hard work for free with people like me. To me this seems like a lot of symbol manipulation and I have no idea how people really see the physical reality that underlies this. It seems like it’s hard enough to keep up with the symbol manipulation, that the physical correlates would kinda fade into the background for a lot of students. Thank you for ur work

Thank you. Your videos helped me a lot! Do you plan to talk about renormalization?

Thank you! ^.^
