Searching for a $$D {\bar{D}}$$ DD¯ bound state with the $$\psi (3770) \rightarrow \gamma D^0 {\bar{D}}^0$$ ψ(3770)→γD0D¯0 decay
Abstract We perform a calculation of the mass distribution in the $$\psi (3770) \rightarrow \gamma D {\bar{D}}$$ ψ(3770)→γDD¯ decay, studying both the $$D^+ D^- $$ D+D- and $$D^0 {\bar{D}}^0 $$ D0D¯0 decays. The electromagnetic interaction is such that the tree level amplitude is null for the neutra...
