Physics Group Meeting

Operators with non-integer spin have been considered in the literature in various forms and contexts, and have been suggested to control the Regge limit and the OPE of average null energy operators. I will discuss the idea of formally introducing such operators in non-perturbative conformal field theory, following 1805.00098, starting from the Lorentzian inversion formula. If time permits, I will also discuss how one can quantitatively study the OPE of average null energy operators using this technology.
