摘要
考虑了D->K0Sππ衰变中直接CP破坏对从B->DK、D->K0Sπ+π- Dalitz图分析中测量γ角的影响。估计了来自D->K0Sπ+π-中直接CP破坏当前上限的γ系统不确定性，并提出了一种修改后的模型无关的B->DK、D->K0Sπ+π- Dalitz图分析程序，该程序即使在粲衰变中存在直接CP破坏也能给出无偏的γ测量。该技术可应用于其他三体D衰变，如D->K0SK+K-、D->π+π-π0等。

Significant change after discussion with journal referee: ambiguity in the CPV-allowed fit due to common CP-violating charm phase is mentioned and way to account for it is proposed.
