Recent and Future Fermilab Drell-Yan Experiments

The (very successful) past:

FNAL E866/NuSeaFNAL E866/NuSea Data in 1996-1997 1H, 2H, and nuclear targets 800 GeV proton beam

The future:

FNAL E906FNAL E906 Data in 2009?? 1H, 2H, and nuclear targets 120 GeV proton Beam

Cross section scales as 1/s

– 7 that of 800 GeV beam Backgrounds, primarily from J/ decays scale as s

– 7 Luminosity for same detector rate as 800 GeV beam

5050 statistics!! statistics!!


Structure of the nucleon: What is d/u in the proton?

Select xb À xt to isolate first term (detector acceptance will do this).

Study ratio of cross sections for deuterium to hydrogen

(In analysis, we use a full Next-to-Leading order cross section calculation with both terms)

Tevatron 800 GeV

Main Injector 120 GeV


E906 ApparatusBoost difference between 800 and 120 GeV requires shorter experiment.

–Previous (E866) spectrometer was over 60m long; E906 spect. is only 26m long–Fabrication of new coils for M1 magnet (was 14.5 m long new M1 is only 4.8 m)–Complications with decays between target and absorber

Other items:–New Station 1 to handle higher rate–Replace some very old scintillators, additional phototubes

FAIR – Prospects and ChallengesFAIR – Prospects and Challenges

• FAIR is a facility, which will serve a large part of the nuclear physics community (and beyond):

- Nuclear structure Radioactive beams- Dense Matter Relativistic ion beams- Hadronic Matter Antiprotons, (polarized)

- Atomic physics- Plasma physics

• FAIR will need a significant fraction of the available man-power and money in the years to come:

1 G€ 10 000 man-years = 100 “man” for 100 years

or (1000 x 10)

• FAIR will have a long lead-time (construction, no physics) staging (3 phases)







High Intensity -Source at Duke

Broad physics program planned for HIS – Nuclear Astrophysics– Few Body Physics– GDH Sum rule for deuterium– Nuclear Structure studies using NRF– Compton scattering from nucleons and few

body nuclei– Pion Threshold studies

time
