Challenge for detector design and technology
Challenge for Detector Design and Technology

  • Editors (John Jaros) + Tim Barklow + Henri Videau + Keisuke Fujii

  • Outlines

    • Jet energy resolution: Required lum. vs resolution.

      • s(nnWW/ZZ), Br(HWW*), s(HHZ), SUSY(WW/ZZ)

    • Momentum resolution:

      • Recoil mass of ZH llX , Slepton Mass, Lum weighted ECM det. from m pair and mmg

      • Challenges imposed by the ILC beam structure

    • Beamcal

      • High rad. Env., reacdout each bunch, need to veto H.E. e at the smallest possible angle

      • S(SUSY) vs veto efficiency, electron angle, ..

    • Others

      • Ebeam, Pol., High B Solenoid., Muons, required R&D

Gakujyutsu Sousei Monthly Meeting


Sub detector performance
Sub-Detector Performance

  • Philosophy

    • Pickup typical results from concept studies in order to show that detector performance used in the physics chapter is confirmed with some extent by full simulations.

  • Basics

    • Material budget of detectors

  • Tracker performacne

    • Momentum resolution: TPC (GLD, LDC, 4th), SiD

    • Track reconstruction

      • TPC: Old Tesla TDR result

      • SiD: VTX based, ECAL Based + SiD standalone

Gakujyutsu Sousei Monthly Meeting


Comparison of momentum resolution
Comparison of Momentum Resolution

GLD

LDC

  • GLD vs LDC

  • Difference in Low Pt region ?Is it by IT matterial ?

  • High Pt: TPC only resol. Different.

  • Spatial resolution difference ?

  • With VTX/IT Constraint, similar performance.

  • No CosTheta dep. From GLD.

SiD

Calorimeter and pfa performance
Calorimeter and PFA Performance

  • Calorimeter performance for single particle

    • g/electron energy resolution & angular resolution

    • Pi+/Kaon_L energy resolution & angular resolution

  • PFA issues

    • Describe what is PFA

    • Typical PFA algorithm(s)

    • Typical PFA performance at Z pole and higher energy

      • Resolution : 90% RMS

      • SiD result ?

      • LDC – 30%/sqrt(E) at Z pole, but not good for ttbar, 500GeV

      • GLD – 30%/sqrt(E) at Z pole, barrel region

        • Not good in endcap region  Hope to improve soon

        • Still tile geometry.  Strip geometry ?

        • High Energy performance not good.  Hope : good for baseline physics

~13 mm at 1 GeV

SiD promissed similar plot by the end of Oct.

Need a plot of cosq dependance.
