Is it really necessary to renormalize a super-renormalizable theory?

  • $\begingroup$ What, specifically, is your proposal on what to do with the finite # of divergences in them? As it stands, your question is inviting a rambling, impossibly broad essay. $\endgroup$ Nov 29, 2018 at 15:35

  • $\begingroup$ i am trying to speculate if we could be better off without renormlization procedure by imposing a finite condition on the correlation functions at a point and hope it works for the rest of the points in position or momentum space. $\endgroup$

  • $\begingroup$ what you are suggesting is the renormalization procedure. $\endgroup$ Nov 30, 2018 at 15:04
  • $\begingroup$ Are you saying that mere introduction of finite conditions, say on the propagators, is enough to designate the procedure as renormalization procedure, even without re-defining the parameters? $\endgroup$
