Towards more precise measurements of gamma

该项目将尝试使用LHCb的Run3数据对伽马进行更精确的测量。这将包括重新设计入库方案，更好地评估背景，可能同时延长。它还将需要来自BESIII的更新测量。该项目还将更仔细地观察LHCb升级时的粒子PID性能，并增强当前的校准工具。这包括改进选择和匹配，更精确地确定系统不确定度，以及部署二次校准通道。

The project will attempt to make more precise measurements of gamma using the Run3 data from LHCb. This will include a redesign of the binning scheme, a better evaluation of backgrounds, a possible simultaneous extension. It will also require updated measurement from BESIII.The project will also take a closer look at the particle PID performance at LHCb upgrade and augment the current calibration tools. This involves improved selection and fit, and more precise determination of systematic uncertainties and also the deployment of the secondary calibration channels.
