Click For Summary
A Lagrangian is considered renormalizable if it includes only triple and quadruple vertices or a maximum of four powers of the fields. The renormalizability criteria are influenced by the dimensionality of the fields involved. For example, a 4-fermion interaction, like that in the Fermi theory of weak interactions, is not renormalizable. Comprehensive information on this topic can be found in quantum field theory textbooks, with Peskin & Schröder being a widely recommended resource. Understanding these conditions is essential for studying quantum field theories effectively.

I read that a Lagrangian is renormalizable if it contains only triple and quadruple vertices, or at most four powers of the fields.
Where can I read more about the precise mathematical conditions?

This depends on the dimensionality of the fields. A 4-fermion interaction (such as the one in the Fermi theory of weak interactions) is not renormalizable. This should be covered in any QFT textbook. Peskin & Schröder is pretty standard, but there are of course others too.
 
Hi everyone, I am doing a final project on the title " fundamentals of neutrino physics". I wanted to raise some issues with neutrino which makes it the possible way to the physics beyond standard model. I am myself doing some research on these topics but at some points the math bugs me out. Anyway, i have some questions which answers themselves confounded me due to the complicated math. Some pf them are: 1. Why wouldn't there be a mirror image of a neutrino? Is it because they are...
