Higher-twist Regge spectroscopy in N = 4 SYM


4/2-037 at CERN

We study a family of higher-twist Regge trajectories in N=4 SYM theory using integrability techniques. We explore the many-sheeted Riemann surface connecting the different trajectories and show the interplay between the degenerate non-local operators known as horizontal trajectories. We resolve their degeneracy analytically by computing the first non-trivial order of the Regge intercept at weak coupling, which exhibits new behaviour: it depends linearly on the coupling. This is consistent with our numerics, which interpolate all the way to strong coupling.
