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

TL;DR

This paper uses a holographic AdS/QCD model with a twist-5 operator to compute odd glueball masses and construct Odderon Regge trajectories, aligning well with existing results.

Contribution

It introduces a twist-5 operator approach in AdS/QCD to calculate odd glueball spectra and derive Odderon Regge trajectories, providing a novel theoretical framework.

Findings

Glueball masses computed with boundary conditions match literature.

Constructed Odderon Regge trajectories consistent with known data.

Demonstrated the effectiveness of twist-5 operators in holographic QCD.

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.
