Dalitz Plot Analysis of D_(s)^± → K⁺ K⁻ π^± — •Andreas Hönle, Daniel Greenwald, Johannes Rauch, and Dmytro Levit — TU München

Singly Cabibbo suppressed (SCS) and doubly Cabibbo suppressed (DCS) decays of charm mesons play an important role in studies of charmed hadron dynamics. The naive expectations for the rates of SCS and DCS decays are of the order of tan2θ_C and tan4θ_C, respectively, where θ_C is the Cabibbo mixing angle.

Recent studies of such decays suffered from limited statistics and can be updated in the current era of large data sets provided e.g. by the Belle experiment.

We will present the current status of D_(s)^± → K⁺ K⁻ π^±.

Preliminary results of a boosted decision tree-based event selection and a Dalitz plot analysis will be shown.
