Scalar mesons as systems with meson-meson admixtures
Nuclear Physics B - Proceedings Supplements, 1991Abstract The resonances in meson meson scattering and the bound states of quarks andantiquarks are described within the same formalism. Comparison with experiment shows that this strategy is very promising for a detailed study of strong interactions and confinement.

Meson-meson and meson-nucleon scattering and the structure of hadrons
Nuclear Physics A, 1998Abstract Effective meson Lagrangians are the appropriate theoretical tool for the non-perturbative regime of QCD which in the present work is applied to meson-meson and meson-nucleon systems. For the meson-meson part we concentrate our interest on the 1.0 GeV region where we investigate the structure of the scalar mesons f 0 (980) and a 0 (980 ...

Pseudoscalar meson-meson scattering
Nuclear Physics A, 1986Abstract It is shown that an unmodified constituent model is not able to give agreement both with scattering lengths, either from PCAC or experiment, and with the experimental value of fπ. Therefore we propose a modified model. Assuming that only a fraction cM of a meson is well represented by the constituent model leads to a model which describes ...

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.

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.

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.
