On emergence of symmetry in Quantum Field Theory

Speaker:Shlomo Razamat
Time:14:30 - 15:30
Location:Lidow Rosen Auditorium (323)

We will discuss the question of classification of conformal field theories in four dimensions. The classification will lead us to conclude that  majority of theories one can think about have bizarre properties which will be inconsistent  with them having a semi-classical weakly coupled description exhibiting all the required symmetries.  We will then discuss how such descriptions can be constructed by giving up manifest symmetry and having it only as an emergent phenomenon.
