Four Dimensional CFT Models with Rational Correlation Functions

  title={Four Dimensional CFT Models with Rational Correlation Functions},
  author={Nikolay M. Nikolov and Ya. S. Stanev and Ivan T. Todorov},
Recently established rationality of correlation functions in a globally conformal invariant quantum field theory satisfying Wightman axioms is used to construct a family of soluble models in four space-time dimensions. We consider in detail a model of a neutral scalar field φ of dimension 2 . It depends on a positive real parameter c, an analogue of the Virasoro central charge, and admits for all (finite) c an infinite number of conserved symmetric tensor currents. Under some assumptions… CONTINUE READING
