Abstract: We report a study for reconstruction of the decay chain of B0 → J/ψK∗+ followed by J/ψ → μ+μ−, K∗+ → KS0π+ and KS0 → π+π−. The vertex displacement in the same decay where the signal B+ vertex is reconstructed using all the available tracks or using only the tracks coming from KS0 gives an opportunity to investigate possible Data/MC difference in the vertex resolution.
Keyword(s): B meson vertex resolution, KS-based reconstruction.
