Description
An efficient Particle identification(PID) is crucial for Belle II as it will be dealing with a much higher event rate than Belle and ultimately with a larger background. PID is advantageous in suppressing background, studying rare decays as well as for the flavour tagging of B-mesons. We study the charged Kaon and Pion identification performances based on the data collected by Belle II experiment corresponding to a luminosity of 208$fb^{-1}$ and compare with Monte Carlo simulations. For the study, the decay mode $D^{*+} \rightarrow D^0[K^− \pi^+ \pi^0]\pi^+$ is reconstructed as it helps to probe the lower momentum region(< 0.5 ). The kaon efficiency and pion mis-identification rates are calculated in bins of momentum and polar angle, for the different PID criteria.
