Measurement of Strong-Phase Differences
摘要
This chapter uses the selection of single- and double-tag events described in Chap. 5 to determine the strong-phase parameters of \({{D} ^0} \rightarrow {{K} ^+} {{K} ^-} {{\pi } ^+} {{\pi } ^-} \) , using the formalism from Sect. 2.8 . The analysis can be split into two parts. First, the single- and double-tag yields are determined for each tag mode. In the second part, these yields are interpreted in terms of the strong-phase difference and other nuisance parameters.
