Reexamination of KKbar Threshold Phenomena with K+K- Atom Included
Abstract
Description
We develop a general framework to study KKbar threshold phenomena with resonances f0, a0 and K+K- atom included. Based on this formalism we predict that the production of the K+K- atom in p+d=3He+X and similar reactions exhi- bits a drastic energy dependence due to the interplay with resonances f0 (980) and a0 (980). We point out that a set of few parameters describes KKbar threshold effects, f0 and a0 mesons, and K+K- atom. Our hope is that precision experimental study aimed at determining these parameters may shed more light on the nature of f0 and a0 resonances.
