Selection of Single and Double-Tag Events
摘要
This chapter describes the selection of charged particles and photons from collisions recorded by the BESIII detector. Furthermore, the strategy for combining these particles into a decay tree of neutral \({{D}} \) mesons is presented. The selected samples of \({{e} ^+} {{e} ^-} \rightarrow {{D}} {{\overline{{D}}}} \) events are required for an analysis of strong-phase parameters of the \({{{D}} ^0} \rightarrow {{{K}} ^+} {{{K}} ^-} {{\pi } ^+} {{\pi } ^-} \) decay.
