TL;DR

This paper calculates even spin glueball masses using an AdS/QCD hardwall model and derives Pomeron Regge trajectories, showing consistency with experimental data and other models.

Contribution

It introduces a twist two operator approach within the hardwall model to compute glueball spectra and Pomeron trajectories, providing new insights into holographic QCD predictions.

Findings

Glueball masses are comparable with existing literature.

Derived Pomeron Regge trajectories agree with experimental data.

Results are consistent across different boundary conditions.

Abstract

We compute the masses of even spin glueball states $ J^{PC} $, with $ P=C=+1 $, using a twist two operator from an AdS/QCD model known as the hardwall model, using Dirichlet and Neumann boundary conditions. Within this approach, we found that the glueball masses are comparable with those in literature. From these masses, we obtained the Pomeron Regge trajectories for both boundary conditions in agreement with experimental data available and other holographic models.
