Tensor meson couplings in AdS/QCD

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 ($g_{f_{2}NN}$) and tensor meson-photon-vector meson coupling ($g_{f_2\gamma \rho }$) 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 spin-2 meson.
