CHIRAL PERTURBATION-THEORY FOR TENSOR MESONS

Interactions and with a(2), K-2, f(2) and f(2)' tensor-mesons with lo w-energy pi, K, eta, eta' pseudo-scalar mesons are constrained by chir al symmetry. We derive a chiral Lagrangian of tensor mesons in which t he tensor mesons are treated as heavy non-relativistic matter fields. Using 1/N-c counting, we derive relations among unknown couplings of t he chiral Lagrangian. Chiral perturbation theory is applied to the ten sor-meson mass matrix. At one-loop there are large corrections to the individual tensor meson masses, but the singlet-octet mixing angle rem ains almost unchanged. We argue that all heavy mesons of spin greater than or equal to 1 share common feature of chiral dynamics.
