Scale vs conformal invariance in four dimensions

Regular Seminar Kostas Skenderis (STAG, Southampton U.)

14:00 IC
room H503

I will discuss the question of whether four dimensional scale invariant unitary quantum field theories are actually conformally invariant. I will present a complete analysis of possible scale anomalies in correlation functions of the trace of the stress-energy tensor in such theories and discuss recent attempts to show that scale invariance implies conformal invariance.
