LC Physics Study Group Meeting - Past Activities and Future Goals

Explore past activities in LC physics study, from JLC-1 to ACFA reports, and discuss future goals such as Higgs physics, supersymmetry, and more. Plan to present results at upcoming conferences. Agenda includes forming working groups, listing items for study, and deciding analysis methods and schedules.

Presentation Transcript

  1. LC Physics Study Group MeetingIntroduction 2003.4.25 at KEK Yasuhiro Okada (KEK)

  2. Past activities on LC physics study (among theorists and experimentalists) . • JLC-1 (92) • World-wide LCWS 91, 93, 95(Morioka),99,00, 02(Jeju) • ACFA LCWS 98(Beijing), 99(Seoul), 00(Taipei), 01(Beijing), 02(Tokyo) • ACFA report on “Physics and Experiments at JLC” (02) • “Roadmap” report, JLC project (03)

  3. Higgs physics Coupling measurements Detection mh=120 GeV,Lint=500/fb

  4. Supersymmetry GUT relation Smuon production SUSY relation Chargino production

  5. Topand W boson Mass and width determination by top threshold scan Sensitivity to triple Gauge boson coupling constants

  6. Things calculated only theoretically, … Higgs self-coupling measurement Y.Yasui, et.al.

  7. Heavy Higgs boson in MSSM LHC LC (Contours of production cross sections) S.Kiyoura, et. al.

  8. Extra-dimensions Determination of the number of extra-dimensions by the missing-mass distribution. K. Odagiri

  9. Heavy Higgs boson production in a photon-photon collider A : solid line H: long-dashed E.Asakawa, et. al..

  10. Physics research at each stage of energy and integrated luminosity Roadmap report

  11. Many issues remain to be studied. • Simulation studies are necessary to evaluate detection efficiencies and backgrounds for some important processes. Roadmap report

  12. Today’s meeting • Hear a report on past/on-going activities from each “group”. ( Higgs, New Physics, Top, Gamma-gamma, Luminosity, +World-wide study on LHC/LC) • Set next goals for each group. • Discuss how to proceed. • We should present many results, for example, at LCWS 2004 and ACFA LCWS 2003.

  13. To be discussed • Form working groups and choose conveners. • List items to be studied. • Decide analysis methods (platform, etc.). • List activities involving both theorists and experimentalists. • Set up rough schedule of activities. • Decide immediate next steps (tutorial school for beginners, etc. ) etc. etc.
