Hadronic Spectra from Deformed AdS Backgrounds

Understand

Because of the presence of modified warp factors in metric tensors, we use deformed AdS$_5$ spaces to apply the AdS/CFT correspondence to calculate the spectra for even and odd glueballs, scalar and vector mesons, and baryons with different spins.

• For the glueball cases, we derive their Regge trajectories and compare them with those related to the pomeron and the odderon.
• For the scalar and vector mesons as well as baryons the determined masses are compatible with the PDG.
• In particular for these hadrons we found Regge trajectories compatible with another holographic approach as well as with the hadronic spectroscopy, which present an universal Regge slope of approximately 1.1 GeV$^2$.
