Glueballs are still an experimentally undiscovered expectation of QCD. Various theoretical approaches (most famously Lattice QCD) predict a spectrum of glueballs. The tensor ($J^{PC}=2^{++}$) glueball is the second lightest, behind the scalar glueball.
Here, using a chiral hadronic model, we compute decay ratios of the tensor glueball into various meson decay channels. We find the tensor glueball to primarily decay into two vector mesons, mainly $\rho \rho $ and $K^*K^*$ channels. We compare these results to experimental data of decay rates of isoscalar tensor mesons. We make statements on the eligibility of these mesons as potential tensor glueball candidates: the resonance $f_2(1950)$ turns out to be, at present, the best match as being predominantly a tensor glueball.
