Systematics of $q\overline{q}$ states in the ${(n,M}^2)$ and ${(J,M}^2)$ planes

In the mass region up to $M<\mathrm{}2400\mathrm{}$ MeV we systematize mesons on the plots ${(n,M}^2)$ and ${(J,M}^2),$ thus setting their classification in terms of $n^{2S+1}{L}_{J}q\overline{q}$ states. The trajectories on the ${(n,M}^2)$ plots are drawn for the following ${(IJ}^{\mathrm{PC}})$ states: $a_0{(10\mathrm{}}^{++}),$ $a_1{(11\mathrm{}}^{++}),$ $a_2{(12\mathrm{}}^{++}),$ $a_3{(13\mathrm{}}^{++}),$ $a_4{(14\mathrm{}}^{++}),$ $\pi {(10\mathrm{}}^{-+}),$ ${\pi }_2{(12\mathrm{}}^{-+}),$ $\eta {(00\mathrm{}}^{-+}),$ ${\eta }_2{(02\mathrm{}}^{-+}),$ $h_1{(01\mathrm{}}^{+-}),$ $\omega {(01\mathrm{}}^{--})/$ $\phi {(01\mathrm{}}^{--}),$ $\rho {(11\mathrm{}}^{--}),$ $f_0{(00\mathrm{}}^{++}),$ $f_2{(02\mathrm{}}^{++}).\mathrm{}$ All trajectories are linear, with nearly the same slopes. At the ${(J,M}^2)$ plot we set out meson states for leading and daughter trajectories: for $\pi ,$ $\rho ,$ $a_1,$ $a_2$ and
