Abstract

In a previous paper a model has been presented which treats the pion as a collective superposition of quark-antiquark pairs. The pion wave function has strong admixtures of many-quark-many-antiquark components. This wave function is used to investigate empirical weak and electromagnetic-decay properties of the pion. The results so obtained are consistent with a small intrinsic pion radius, substantially smaller than the measured pion charge radius.
