Glueball spectra and Regge trajectories from a modified holographic softwall model

Abstract In this work we propose a modified holographic softwall model, analytically solvable, to calculate the masses of lightest scalar glueball and its radial excitations and of higher spin glueball states for both even and odd spins. From these results we obtain their respective Regge trajectories, associated with the pomeron for even spins and with the odderon for odd spins. These results are in agreement with those calculated using other approaches.

Odd spin glueball masses and the odderon Regge trajectories from the holographic hardwall model

We use the holographic hardwall model to calculate the masses of light glueball states with odd spin and P= C= -1 associated with odderons. Considering Dirichlet and Neumann boundary conditions we obtain expressions for the odderon Regge trajectories consistent with those calculated using other approaches.

Pomeron and odderon Regge trajectories from a dynamical holographic model

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.

Dynamical corrections to the anomalous holographic soft-wall model: the pomeron and the odderon

In this work we use the holographic soft-wall AdS/QCD model with anomalous dimension contributions coming from two different QCD beta functions to calculate the masses of higher spin glueball states for both even and odd spins and their Regge trajectories, related to the pomeron and the odderon, respectively. We further investigate this model taking into account dynamical corrections due to a dilaton potential consistent with the Einstein equations in five dimensions. The results found in this work for the Regge trajectories within the anomalous soft-wall model with dynamical corrections are consistent with those present in the literature.
