Exact Renormalization Group Equations and Gauge Symmetry

Giorno 11 novembre 2019, con inizio alle ore 16:00, presso l'Aula F del #DFA, su invito del Dr Dario Zappalà (INFN-CT), il Dr Shima Asnafi (IPM, Tehran, Iran) terrà un seminario dal titolo Exact Renormalization Group Equations and Gauge Symmetry.

Tutti gli interessati sono invitati a partecipare.

Abstract. After a brief introduction to the Wilsonian Renormalization Group, I will derive an Exact (non-perturbative) Renormalization Group Equation (ERGE) and show how we can find fixed-points and critical indices non-perturbatively by this approach, for a one component scalar theory. We will see the gauge symmetry is not respected, in the case of gauge theories, by EGRE and we will explore how we cure this problem.
