Greenblatt renormalization group
WebOct 1, 2024 · The renormalization group, which had been associated with a cautiously optimistic attitude towards the consistency of QFT question, was likely damned by association in the eyes of many. When Bjorken and Drell dedicated the final subsection of their 1965 QFT textbook to the renormalization group they no doubt further solidified its … WebThe "Renormalization Group" Game Okay, now I want to talk about the renormalization group. I'm deliberately going to simplify things to the point where I'm verging on inaccuracy, but hopefully I won't actually say anything actually false. So, let's recall what we've got. We have a quantum field theory described by a Lagrangian with a bunch of ...
