A novel measurement of the strong-phase difference between $D^{0} \to K^{-} I ¨ ^{+}$ and $D ˉ^{0} \to K^{-} I ¨ ^{+}$ decays using $C$ -even and $C$ -odd quantum-correlated $D D ˉ$ pairs

BESIII Collaboration, M. Ablikim, M. N. Achasov +698

A novel measurement technique of strong-phase differences between the decay amplitudes of $D^{0}$ and $D ˉ^{0}$ mesons is introduced which exploits quantum-correlated $D D ˉ$ pa…
