  • Abstract
    The ZEUS micro-vertex detector (MVD) has been installed during a luminosity upgrade in 2000-01 the proton electron storage ring HERA. It has been reliably operated in the HERA-II run period from the year 2002 to 2007. The design of the MVD is described briefly. The tagging capability for charmed particles, obtained exploiting this detector is presented in this paper. The MVD is particularly important for resolving two shortly displaced vertices which are typical for decays of charm particles. Different charm particle decay topologies and the corresponding vertex finder techniques adopted are discussed.
