#### High Energy Theory Seminar - Tolya Dymarsky, Cambridge - On the four-point correlation function of the stress-energy tensor in a CFT

We discuss to what extent the full set of symmetries, i.e. conformal symmetry and general diffeomorphisms constraint the form of the four-point correlation functions of stress-energy tensors and conserved currents in a general conformal field theory. The conformal symmetry alone expresses the correlation function of four stress-energy tensors in terms of over six hundred scalar functions of the conformal cross-ratios. Imposing conservation restricts the number of the unconstrained degrees of freedom to 29 scalar function. Similarly, four-point function of the conserved currents depends on just 7 unconstrained scalar functions. The relatively small number of the surviving degrees of freedom raises hopes of formulating conformal bootstrap for these correlates in a self-contained practical way.
