  "abstract": "Light vector- and tensor-meson resonance contributions to the three-body decays $χ_{cJ}\\to P_1P_2V$ are studied in a quasi-two-body framework combined with SU(3) flavor relations for the two-body subprocesses, covering both the $χ_{c0,1,2}\\to VV\\to P_1P_2V$ and $χ_{c1,2}\\to TP\\to P_1P_2V$. Both the narrow-width approximation (NWA) and the finite-width effects (FWE) treatment are considered, the latter being essential for tensor subdecays that are kinematically closed at the nominal mass and contribute only through the high-mass tail of the resonance. The predicted resonance bands span several orders of magnitude, with the largest ones in the $ππρ$, $πK\\bar K^{*}$, and $K\\bar Kϕ$ final states, whereas the $K\\bar Kω$ and $η'KK^{*}$ channels are dominated by the tensor band and thus provide a clean window onto the $T\\to PV$ tensor resonances. The band-by-band strengths and their ordering are intended as priors and channel priorities for future invariant-mass and amplitude analyses, and can be compared with the measured totals of several channels.",
