Decays of the tensor glueball in a chiral approach

Published online: 16 February 2024
Glueballs remain an experimentally undiscovered prediction of QCD. Lattice QCD predicts a spectrum of glueballs, with the tensor (JPC = 2++) glueball being the second lightest, behind the scalar glueball. From an effective hadronic model based on spontaneous and explicit chiral symmetry breaking, we compute decay ratios of the tensor glueball into various meson decay chan nels. We find the tensor glueball to primarily decay into 2 vector mesons, dom inated by ρρ and K* K*. These results are compared to experimental data of decay rates of spin 2 mesons. Based on this comparison we make statements on the eligibility of these mesons as potential tensor glueball candidates.
