Hidden-charm scalar tetra-quark mesons
Abstract
Decays of hidden-charm scalar tetra-quark mesons as the partners of Ds0(2317) which has successfully been assigned to the iso-triplet scalar tetra-quark [c,n][sbar,nbar]I=1 meson are studied. Because OZI-rule allowed strong decays are kinematically limited, their radiative decays are expected to be important.
