New High-Energy Dimuon Experiments at Fermilab and J-PARC
Ming X. Liu (LANL)

Abstract: I discuss selected physics topics from the future high-energy dimuon measurements at the Fermilab and J-APRC. The Fermilab E906 experiment will use Drell-Yan scattering to measure nucleon and nuclear structure at the parton level, and study the effects of energy loss of fast quarks traveling nuclear medium. This experiment will use the 120GeV proton beam extracted from the Fermilab main injector. The E906 experiment has been approved by the Fermilab PAC and is scheduled to collect data in 2009. The proposed high-mass dimuon measurement at J-PARC will use the 50-GeV proton synchrotron that is under construction now. With the possibility of having polarized proton beams at J-PARC, we explore a new spin physics program with dimuon measurements.
