Abstract
Basing on the latest results of the PNPI (Gatchina) and QM and W College (London) groups, I discuss systematics of the IJPC qq-bar states in terms of trajectories on the (n,M2) plane, where n is the radial quantum number and M is its mass. In the scalar sector, which is the most interesting because of the presence of extra states with respect to the qq-bar systematics, I discuss: 1) the results of the K-matrix analysis of the spectra {pi}{pi}, {pi}{pi}{pi}{pi}, KK-bar, {eta}{eta}, {eta}{eta}', {pi}{eta} and characteristics of the resonances in the scalar sector, 2) qq-bar-nonet classification of scalar bare states, 3) accumulation of widths of the qq-bar states by the glueball due to the overlapping of f0-resonances at 1200-1700 MeV, 4) systematics of scalar qq-bar states, both bare states and resonances, on the (n,M2)-plots, 5) constraints on the quark-gluonium content of the resonances f0(980), f0(1300), f0(1500), f0(1750), and the broad state f{sub 0}(1420{sub -70}{sup +150}) from hadronic decays, 6) radiative decays of the P-wave qq-bar-resonances: scalars f0(980), a0(980), and tensor mesons a2(1320), f2(1270), f2(1525). The analysis proves that in the scalar sector we face two exotic mesons: the light {sigma}-meson, f0(450), and the broad state f{sub 0}(1420{sub -70}{sup +150}), which
