@article{Anisovich2002REVIEWSOT, title={REVIEWS OF TOPICAL PROBLEMS: Systematics of quark-antiquark states and scalar exotic mesons}, author={Vladimir V. Anisovich}, journal={Physics-Uspekhi}, year={2002} }

Analysis of experimental data from the Crystal Barrel Collaboration on the in-flight pp annihilation into mesons revealed a large group of mesons in the 1900 – 2400-MeV range, allowing the systematization of quark–antiquark states in the (n, M2)- and (J, M2)-planes (n being the radial quantum number, and J the spin of a meson of mass M). From the data, meson trajectories in these planes are approximately linear and have a universal slope. A detailed discussion of the scalar meson sector is…
