Abstract	We report a particle identification (PID) tool developed using energy-loss information in the silicon-strip vertex detector (SVD) of Belle II for charged pions, kaons, and protons using \(D^{* + } \to D^{0}[ \to K^{ - }\pi ^{ + }]\pi ^{ + }\) and \(\Lambda \to p\pi ^{ - }\) decay samples. The study is based on e^+e^− collision data recorded at the \(\Upsilon (4S)\) 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.
