Empirical light meson trajectories: radial 3P2, 3P0, 3F2

Candidate light meson states are selected to form linear trajectories in squared mass m2 vs. radial excitation number N. The most numerous candidates have JPC=(even)++ and J⩽2: namely, 3P2, 3P0 and 3F2. About 40 states are assembled into 11 trajectories distinguished by four flavors: f, a, K and f′; no candidates appeared for 3F2 :K. From these data the universal slope of the Veneziano model emerges as A=dm2/dN=1.04±0.01 GeV2.
