Abstract The ψ′ → ψπ0 decay rate is studied in a chiral symmetry breaking scheme by including effects from π0-η mixing only. The result obtained is in very good agreement with the experiment.

Abstract We explore new implications for the mu=0 hypothesis and show that the decay rate for η→3π0 is in remarkable agreement with the experiment.

Abstract In this letter, we observe that if the E(1440) is identified as a glueball with pseudoscalar quantum numbers then its decay width can be significantly large, about as broad as that of the ϱ meson, if not more. However, the possiblity of a narrow width cannot be rigorously ruled out. We also examine the sensitivity of the decay widths to the off-shell corrections as well as to the sign of the intermediate coupling constants.

We consider the effects ofη−π mixing on the violation of the |ΔI|=1/2 rule in |ΔS|=1 weak transitions. The processes considered are theK→2π,K→3π, Λ, Ξ and Λ hyperon decays.

A local derivative coupling model is used to study theφ′→ππ and other dipionic decays ofφ andφ″, as an alternative to theε-model. The results obtained are quite satisfactory. We findt hat the existence of theε-resonance is not essential in order to understand the dipionic decays of the psions at the present level of experimental data available.
