Updated model-independent measurement of the strong-phase differences between D 0 and D ¯ 0 → K S / L 0 π + π − decays

Journal article

The strong-phase differences between D0→KSL0π+π− and D¯0→KSL0π+π− decays are one of the most important inputs in measuring the CP violating angle γ via B− → DK− decays. They also play a key role in studies of charm mixing and indirect CP violation. In this paper, the strong-phase differences are determined in a model-independent way with quantum-correlated D0-D¯0 decays from 7.93 fb−1 of e+e− annihilation data at s = 3.773 GeV by the BESIII experiment. These results are the most precise to date and are expected to significantly reduce associated uncertainties in determining the CP violating angle γ and related charm mixing parameters.
