Abstract: Ability to reconstruct the track impact parameter with high resolution is essential for CP violation studies at Belle II. Early Phase 3 data are used to estimate it using d0 reconstructed in two-track events with both tracks detected by the PXD and SVD detectors. The data are compared with the expectations from the Bhabha simulation.
