Strong Pionic Decays From a Spectroscopic Quark Model
F. Cano, P. González, S. Noguera, B. Desplanques
Abstract
From a refined non-relativistic quark model that fits the baryonic low-energy spectrum the study of strong pion decay processes within an elementary emission model scheme points out the need of incorporating size-contributing components into the baryon wave functions. In particular the effect of a (qqq qantiq) component is investigated in the framework of a quark pair creation model.
