1207.1311 (Vlasios Petousis)

A generalized dilaton gauge field for the rho meson mass spectrum in the
soft-wall AdS/QCD
   [PDF]

Vlasios Petousis
Meson spectroscopy within the frame of the soft-wall AdS/QCD, became one of the most interesting topics of particle physics in the last six years. In this work we attempt a generalized parametric analysis of the background dilaton gauge field. Aim of this work is that using a positive z-depended dilaton gauge field and setting the appropriate parameters on it, we are able to reproduce the full vector meson mass spectrum. Also the correct Regge trajectories can be reproduced without problems with massless modes in the vector sector. To reinforce the results, we compare the proposed parametric model with the experimental data. This comparison, returns in some cases an error less than 1%.
