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 ∗+→0[→−+]+ and Λ→− decay samples. The study is based on e+e− collision data recorded at the Υ(4) 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.

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 ∗+→0[→−+]+ and Λ→− decay samples. The study is based on e+e− collision data recorded at the Υ(4) 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.File in questo prodotto:
