The measurement exploits a data sample equivalent to an integrated luminosity of 2.93 fb-1, collected by the BESIII detector in e+e- collisions corresponding to the mass of the ψ(3770) resonance. The strong-phase difference is an essential input to the determination of the Cabibbo-Kobayashi-Maskawa (CKM) angle γ/φ3 through the decay B-→DK-, where D can be either a D0 or a D¯0 decaying to KS,L0K+K-. This is the most precise measurement to date of the strong-phase difference in these decays. ",

N2 - We present a measurement of the strong-phase difference between D0 and D¯0→KS,L0K+K- decays, performed through a study of quantum-entangled pairs of charm mesons. The measurement exploits a data sample equivalent to an integrated luminosity of 2.93 fb-1, collected by the BESIII detector in e+e- collisions corresponding to the mass of the ψ(3770) resonance. The strong-phase difference is an essential input to the determination of the Cabibbo-Kobayashi-Maskawa (CKM) angle γ/φ3 through the decay B-→DK-, where D can be either a D0 or a D¯0 decaying to KS,L0K+K-. This is the most precise measurement to date of the strong-phase difference in these decays.
