Description
The selection of $D^{+}\longrightarrow K^{−}K^{+}K^{+}$ candidates is performed using a multivariate analysis. The study is based on a sample of pp-collision data, collected at a centre-of-mass energy of 13 TeV with the LHCb detector in 2016. Different multivariate classifiers are considered and their signal-background discrimination performance is evaluated. The signal significance is investigated and its optimization is examined for each classifier. The result is a final selection of $D^{+}\longrightarrow K^{−}K^{+}K^{+}$ candidates useful for a further analysis, e.g, CP violation and amplitude analysis studies.
