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 ( $g_{f_{2} N N}$ ) and tensor meson-photon-vector meson coupling ( $g_{f_{2} γ ρ}$ ) 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.
