摘　　要：Because of the presence of modified warp factors in metric tensors,we use deformed AdS5 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.
