GLD DOD

This presentation discusses the preliminary tools and results from the Jupiter detector performance study presented at the 2nd GLD DOD meeting. Key tools include the JSF/Quick Simulator and various analysis techniques for single particle performance, momentum resolution, and jet mass resolution. We explore detector configurations, including momentum resolution tracking, energy resolution for EM and HD calorimeters, and factors affecting jet mass resolution. The study highlights results for Higgs events, jet mass dependence, and outlines future developments needed for comprehensive physics performance studies.

  2. Section 1 • Tools for performance study • JSF/Quick Simulator • Jupiter • Detector Model • Jupiter Detector Figure (Fig. 1-1) • Summary table of Detector configuration for Jupiter (Table 1-1) • Satellites: Description of Analysis Tools • Satellites analysis flow • Track fitter and Kalman fitter  Yamaguchi’s Master Thesis • Cheated PFA algorithm description • Realistic PFA algorithm description  Fujikawa’s Master Thesis

  3. Fig 1-1

  4. Table 1-1 : Table of detector configuration parameter

  5. Section 2: • Single particle performance by Jupiter • Momentum Resolution by TPC+IT+VTX by A.Yamaguchi • Vs Pt (Fig 2-1), vs CosTheta • Impact parameter resolution by Nagamine (Fig. 2-2) • Momentum Resolution by IT for forward region by YounGim (Fig 2-X) • EM Calorimeter Energy Resolution by gamma • HD Calorimeter Energy Resolution by K0L • Radiation length of the system ( by Y.Yamaguchi) • Interaction length of the detector ( by Y.Yamaguchi) • Muon efficiency vs Pt

  6. Section 2-2 • Quick Simulator Performance • dPt/Pt vs Pt (Fig 2-2-1) • dPt/Pt vs CosTheta • Impact Parameter resolution (Fig 2-2-3)

  7. QSIM Pt Resolution

  8. QSIM IP resolution

  9. Section 2-3: • Jet mass resolution by Jupiter • Using e+e-  u, d, s quark events, without ISRselected events where |CosTheta_quark| < 0.8 • Visible mass by Cheated method at 91, 350, 500 GeV ( Fig 2-3-1) • Factors which affect jet mass resolution by S.Yamamoto • Contribution of HD/EM/Tracker resolution to Jet mass (Table 2-3-1) • Contribution of Pt cut off of tracker • Study by Realistic PFA ( to be written by Yoshioka san ) • Jet mass resolution for 91 GeV is about 38%/Sqrt(E)

  10. Jet mass by Jupiter Higgs events

  11. Jet mass by QuickSim

  12. Jet mass : Qsim worse resol.

  13. Quick Simulator is tuned to reproduce Jupiter result based on cheated PFA. • Energy dependance of jet mass resolution of Quick Simulator is about same as that of Jupiter • Another parameter set of Quick Simulator is prepared for more realistic physics performance study

  14. Section 3 • Physics Performance study by Quick Simulator • Higgs process • To be presented by Yoshioka san • SUSY Process • Stau : ?? • need stau generator • Need two photon process generator • Study by Jupiter • Higgs self coupling ?? • Event generator exists, but need debugging • Another question • Beamstrahlung spectrum for ILC parameters • Crossing angle not considered

  15. Section 4 • Variation of GLD detector • Study jet mass resolution by cheated method • R_EM=1.7 and 2.3 ( R_TPC, … increased accordingly.) • B=5Tesla • Inner radius of Vertex detector and influsence to the Higgs events selection • Validation of GLD detector configuration
