High Energy Theory Seminar

 In this talk I would like to discuss about the computation of anomalous dimension and OPE coefficients at finite conformal spin in arbitrary space-time dimensions, by means of the OPE inversion formula and the (Mellin) representation of conformal blocks. We will mainly show show that the contribution from individual exchanges to anomalous dimensions and corrections to the OPE coefficients for "double-twist" operators in can be written at finite conformal spin in terms of generalized Wilson polynomials. If time permits, I also would like to present a conjectural formula relating flat-space amplitudes to landau singularities of conformal correlation functions.
