• JSF control panel.
• The reconstructed higgs mass distribution, of the process e+e- -> neu neu-bar h, where h decays hadronically. Pythia and Quick Simulator is used. ( see transparencies at 1st ACFA WS for more details.)

• Typical Zh event at 300 GeV center of mass energy.
  • All detector view
    cyan and red boxes are HDC and EMC hit cells, green lines are CDC tracks. Inner radius and outer radius of wire-frame cylinder corresponds to the inner radius of EMC and HDC, respectively.
  • Region near Interaction region
    yellow lines are generated charged track, purple squares are VTX hits, with 200 micron meter square. Two cylinders shown by wire-frame are VTX's inner most and outer most layers.

• VTX background hits
  Beam-induced background hits on the first layer of VTX detectors are super imposed on Zh events. Background hit density is 1 hit per 1 mm square. The radius of the first VTX layer is 2.4 cm.
  • Standard Vertex view.
  • A bit closer to the VTX.
  • A very close to the VTX.
  Green boxes are background hits and blue boxes are signal hits. The signal boxes are 40 micron-meter cubic. For the signal hits, larger boxes, 400 micron-meter square and 40 micron-meter height, are also displayed to indicate amounts of signal overlapping. Since we are using wire frame 3 D view, signals on the opposite side of VTX layer are displayed as dots. Signals on the same side of VTX layer have visible size.
  From these pictures, we can see that signal hits are safely separated from background hits.
