Revisiting the tensor-meson nonet in resonance chiral theory

We study the properties of lowest multiplet light-flavor tensor meson resonances, i.e. $f_2(1270)$, $a_2(1320)$, $K_2^*(1430)$, and $f_2'(1525)$, within resonance chiral theory approach. The higher-order operators, including light-quark mass $1/N_C$ corrections, are simultaneously incorporated in our study. use expressions allows us to analyze not only relevant experimental data but also meantime lattice results at unphysical quark masses, masses resonances their decay widths into two pseudoscalar mesons. In addition, radiative decays one photon plus photons studied.
