On the spins of meson-meson resonances
Il Nuovo Cimento, 1963The disintegration of two-meson resonances, produced in twobody reactions, is studied. It is shown that the resonance-spin can be obtained from measurement of the polar angle for the disintegration in the resonance rest-system, for a sufficiently large number of events selected in an appropriate way.

Values of the proper lifetime of the meson have been deduced from a comparison of the intensity of mesons in an inclined direction under air with that in the vertical under a superposed lead shield equivalent in absorbing power to the difference between the masses of air traversed by the mesons before reaching the apparatus in the two directions.

Threshold effects in meson-meson and meson-baryon scattering
AIP Conference Proceedings, 1991We investigate within a genrealized meson–exchange model meson–meson and meson–baryon scattering. We concentrate our investigations on the behavior of such systems when a new particle channel opens. Specifically we demonstrate these effects at the KK‐threshold in ππ‐scattering and the KN‐threshold in πΣ–scattering.

Status of Meson-Meson Interaction
1974The plan of these lectures is as follows: In 1. I shall briefly review the current experimental situation for \(\pi \pi \to \pi \pi ,\pi \pi \to K\overline{K}and{{K}_{\pi }}\to {{K}_{\pi }}\) phase shift analysis; in 2. I shall give an account of some of the dispersion techniques which are evolving for the imposition of crossing symmetry and in 3.

Are the new mesons qq̄ or meson meson bound states (deusons)
AIP Conference Proceedings, 1995The new mesons which cannot find a place within the qq model, the f0(1370),f0(1525),f0(1590),f2(1520),ν(1440), and f1(1420), are discussed and it is suggested that some of these are deuteronlike two‐meson bound states, deusons. The contribution from one pion exchange to the binding energy between two ground state mesons is calculated.
