Abstract

We study the hadronic and radiative couplings of the f(2)(1270) meson within the hard- and soft-wall models of AdS/QCD. The results for the tensor meson-nucleon-nucleon coupling (g(f2NN)) and tensor meson-photon-vector meson coupling (g(f2 gamma rho)) are compared to the ones obtained by using the dispersion relations and amplitude methods, respectively. Qualitative agreement with different analyses implies the reliability of the holographic description of the spin-2 meson.
