Proton identification by MVD for penta-quark
study (R.Hori, S.Chekanov)

• We try to MVD dE/dx in order to select more
  proton candidate.
• Using MVD can find more protons only CTD.
• Some corrections for MVD hits developed.
• For ladders, Run by run,
• We try to use maximum likelihood method for MVD
  hit in order to calculate more exact dE/dx.
• This plot is MVD dE/dx result as a temporal.
