ee? linear collider Politics
1/4

• Politics
• ECFA, ACFA, HEPAP OECD agree ee? linear
  collider is next logical step in accelerator
  based particle physics
• All laboratories and nationalities involved agree
  ee? linear collider to be a world project
  (Global accelerator/detector concepts)
• Cold TESLA concept is at present the only mature
  proposal. However, everyone expects three
  comparable (, L, ?s) proposals to be available
  by the end of 2003.

• Physics
• Everyone says pp and ee? collider should run
  concurrently.

• Reality
• State which offers most , or will become the
  host!
• First beam optimistically before end of LHC
  running (2015?).

5
ee? linear collider Standard Model Physics
2/4
Standard Model internal consistency (Giga Z
standard running)

• W-boson ?mW ? 5 MeV
• Standard WZ couplings
• Z-boson ?sin2?w ? 10?5
• t-quark mass ?mt ? 100 MeV
• Anomalous WZ-couplings

• Higgs mass ?mH ? 50 MeV
• Higgs couplings ? 2
• Higgs potential ? 20
• Higgs spin-parity analysis

• Theoretical effort
• 2-loop calculations e.g. ?r
• ?? (ee? annihilation _at_ low ?s)
• many new MC generators
• e.g. automatic MC packages

6
ee? linear collider New Physics
3/4
note E-scale!

• Higgs sector h0, H0, A0, H?
• Unravel the ambiguities left
• behind by the LHC!

7
ee? linear collider Detector RD
4/4
8
NIKHEF joins the global ee? linear collider
endeavour (Collary NIKHEF helps to convince
CERN to do so as well!)
9
Neutrino status
1/4

• Status
• Three ?-species (LEP 2.981 ? 0.008
  4He/1H 3.3 ? 0.2 or so)
• ?-mass limits (tritium ?-decay lt
  2.8 eV astrophysics lt 1 eV)
• Solar ?-oscillations (Homestake, Gallium,
  (Super)Kamiokande, SNO)
• Atmospheric ?-oscillations (IMB, Macro,
  (Super)Kamiokande, Sudan)
• LSND anomaly (wait for MiniBoones
  result ignore it for the moment)
