Wave-packet effects: a solution for isospin anomalies in vector-meson decay
Abstract There is a long-standing anomaly in the ratio of the decay width for $$\psi (3770)\rightarrow D^0\overline{D^0}$$ ψ ( 3770 ) → D 0 D 0 ¯ to that for $$\psi (3770)\rightarrow D^+D^-$$ ψ ( 3770 ) → D + D - at the level of $$9.5\,\sigma $$ 9.5 σ . A similar anomaly exists for the ratio of $$\p...
