TL;DR
This paper studies the decay properties of hidden-charm scalar tetra-quark mesons, emphasizing their radiative decays due to limited strong decay channels, and relates them to the D_{s0}(2317) meson as a tetra-quark partner.
Contribution
It proposes a detailed analysis of hidden-charm scalar tetra-quark mesons and highlights the significance of radiative decays in their detection, building on the D_{s0}(2317) as a tetra-quark partner.
Findings
Radiative decays are significant due to limited strong decay channels.
The D_{s0}(2317) is identified as an iso-triplet scalar tetra-quark.
Strong decays are suppressed by the OZI rule.
Abstract
Decays of hidden-charm scalar tetra-quark mesons as the partners of D_{s0}(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.
