Abstract	We study the performances of the charged Kaon and Pion identification based on 2.62 fb−1 Phase III data from the Physics runs taken during summer 2019 and compare with Phase III Monte Carlo events. The efficiency and the fake rates of kaon and pion identification are calculated using D ∗+ → D 0 [K − π + ]π + decays for the binary PID criteria (obtained from ALL the subdetectors combined). The study is performed in the momentum and polar angle bins.
