AdS/QCD oddball masses and Odderon Regge trajectory from a twist-five operator approach

Abstract

In this work, we consider a massive gauge boson field in AdS${}_5$ dual to odd glueball states with twist-5 operator in 4D Minkowski spacetime. Introducing an IR cutoff we break the conformal symmetry of the boundary theory allowing us to calculate the glueball masses with odd spins using Dirichlet and Neumann boundary conditions. Then, from these masses we construct the corresponding Regge trajectories associated with the odderon. Our results are compatible with the ones in the literature.
