Abstract	We report a particle identification (PID) framework developed using energy loss information in the silicon-strip vertex detector (SVD) of Belle II for charged pions, kaons and protons using D∗+ -> D0[-> K pi+]pi+ and Lambda -> p pi- decay samples. The study is based on 6.1 fb−1 data recorded at the Y(4S) resonance by Belle II and the results are compared with that of a Monte Carlo sample. The introduction of additional information from the SVD is found to improve the overall PID performance in the low momentum region.
