Title: Regge trajectories for N=(2,0) superconformal field theories

Abstract:

The spectrum of conformal field theories displays Regge trajectories: families of operators whose dimensions are smooth functions of the spin. We discuss the structure of Regge trajectories of the six-dimensional N=(2,0) SCFTs, in particular of operators coupling to the stress tensors super-multiplet. We show how these operators organize themselves in Regge trajectories starting at spin -3, and how different Regge trajectories are intertwined by supersymmetry. We then describe an iterative procedure to “bootstrap” the stress tensor multiplet four-point function using the Lorentzian inversion formula. Taking as input protected data we obtain an approximate low twist spectrum and compare it rigorous numerical bootstrap bounds.
