New posts in Renormalization

What does Pauli-Villars Regularization physically mean?

Why does the divergence of a QFT's coupling constant under RG flow trivialize the theory if it occurs in the UV but not in the IR?

Triviality of Yang Mills in $d>4$?

Are there any known models with limit cycles in their RG flow?

Why does the fine-structure constant $α$ have the value it does?

Why is Wilson's work so relevant in particle physics? I thought that critical phenomena were described by CFTs

Understanding renormalizability and bare mass

Dirac once said that renormalization is just a stop gap procedure, and there had to occur a fundamental change in our ideas. Did something change?

"Dimensional analysis" arguments in quantum field theory

What is the Wilsonian definition of renormalizability?
