Description
In this work we discuss how to construct the Regge trajectories for light mesons and baryons in the context of a bottom-up holographic model consisting on a five-dimensional AdS background deformed with a quadratic function in the holographic coordinate. We fit the scalar meson $f_0$, vector meson rho, baryons with spin $1/2^+$ and spin $3/2^+$ trajectories. These results are in fine agreement with those exposed in PDG. We also found in this model a universal Regge slope near to 1.1 GeV$^2$.
