“…Instead, the strong-phase differences may be measured directly in the decays of quantum-correlated neutral D-meson pairs created in the decay of the ψð3770Þ resonance [3,6]. This approach ensures a modelindependent [9][10][11][12][13] measurement of γ where the uncertainty in the strong-phase knowledge can be reliably propagated.…”

Determination of Strong-Phase Parameters in D→KS,L0π+π−

“…These strong-phase parameters were first studied by the CLEO collaboration using 0.82 fb −1 of data [13,14]. The limited precision of CLEO's results contributes a systematic uncertainty of approximately 4°to the γ measurement [15], currently the dominant systematic limitation in this determination. In the coming decades, the statistical uncertainties of measuring γ will be greatly reduced by LHCb and Belle II, potentially to 1°or less.…”

“…In the coming decades, the statistical uncertainties of measuring γ will be greatly reduced by LHCb and Belle II, potentially to 1°or less. The model-independent approach provides the most precise stand-alone γ measurement [15], and therefore improved measurements of the D strong-phase parameters are essential in maximizing the precision of γ from these future data sets.…”

“…The total integrated luminosity of our sample is 2.93 fb −1 [17], 3.6 times that of the CLEO measurement. The expected improvement in precision of the strong-phase parameters will significantly reduce the uncertainties of determinations of γ [15,[18][19][20][21] that utilize D → K 0 S;L π þ π − . Additionally, improved knowledge of these strong-phase parameters will have significant impact in other applications, including measurements of the CKM angle β (also denoted ϕ 1 ) through time-dependent analyses of B 0 → Dh 0 [22] (where h is a light meson) and B 0 → Dπ þ π − [23], as well as measurements of charm mixing and CP violation [24][25][26][27].…”

“…Therefore, the uncertainty on γ arising from knowledge of the charm strong phases is approximately a factor of three smaller than was possible with the CLEO measurements. For the first time, the dominant systematic uncertainty for γ measurement from the strong-phase parameters will be constrained to around 1°, or less, for γ measurements with future B experiments [15,[18][19][20][21]. The predicted statistical uncertainties on γ from LHCb prior to the start of highluminosity LHC operation in the mid 2020s, and from Belle II are expected to be around 1.5° [35,36].…”
