Idea

By a tensor meson the literature typically means a type of meson whose Wigner classification is a Lorentz-spin group spin-2 representation, hence given by a symmetric rank-2 tensor.

Indeed, in the AdS/QCD correspondence these “tensor mesons” are dual to graviton-modes in the \sim bulk spacetime.

Beware that there are also mesons given by anti-symmetric rank-2 tensors (the h1-meson and b1-meson), but since these are “spin-1”, they are counted as vector mesons.

More generally, there are higher spin mesons?, which hence could also be called “tensor mesons”.
