Pomeron and Odderon Regge Trajectories from a Dynamical Holographic Model

TL;DR

This paper employs a dynamical holographic model based on gauge/string duality to compute glueball spectra and Regge trajectories, providing insights into pomeron and odderon exchanges in high-energy physics.

Contribution

It introduces a dynamical holographic approach that incorporates metric corrections due to a quadratic dilaton to calculate glueball states and their Regge trajectories.

Findings

Calculated glueball masses for even and odd spins.

Constructed Regge trajectories for pomeron and odderon.

Results agree with experimental data and other models.

Abstract

In this work we use gauge/string dualities and a dynamical model that takes into account dynamical corrections to the metric of the anti de Sitter space due to a quadratic dilaton field and calculate the masses of even and odd spin glueball states with $P=C=+1$, and $P=C=-1$, respectively. Then we construct the corresponding Regge trajectories which are associated with the pomeron for even states with $P=C=+1$, and with the odderon for odd states with $P=C=-1$. We compare our results with those coming from experimental data as well as other models.
