Pseudoscalar meson-meson scattering

Nuclear Physics A, 1986
Abstract 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 ...

Duality and the pseudoscalar mesons

Il Nuovo Cimento A, 1976
The Lovelace-Veneziano model for the pseudoscalar-meson process PP → PP is considered with particular attention to the problematical requirement of ideal mixing for the pseudoscalar nonet. A solution to the problem which retains the narrow-resonance approximation for this process is found.

Radial excitations of pseudoscalar mesons

Nuclear Physics A, 2000
The current status of radial excitations of pseudoscalar mesons is reviewed. From the observed pseudoscalar states, π(1300), K(1460), η(1295), η(1440), and η(1760), possible nonets of the first radial excitations are examined, together with open problems.

KLOE results on scalar and pseudoscalar mesons

Chinese Physics C, 2010
The data collected by the KLOE Collaboration at the Frascati -factory DAΦ from 2001 to 2006 have been used for extensive studies in meson spectroscopy. The decays of the scalar mesons a0(980) and f0 (980) into two pseudoscalar mesons have been exploited to measure the relevant parameters of those resonances. The radiative decays → ηγ and η'γ have been

ON THE WAVEFUNCTION OF LIGHT PSEUDOSCALAR MESONS

Modern Physics Letters A, 1990
It is shown that electroweak interactions lead to a hard (decreasing at most logarithmically with increasing q2 at [Formula: see text]) part in the Bethe-Salpeter wave function of light pseudoscalars. However, this part is strongly suppressed by the factor [Formula: see text], where F EW ≃ 250 GeV and mc is a quark current mass.
