Description

Fermilab E906/SeaQuest is a fixed-target dimuon experiment using the 120 GeV proton beam from the Fermilab Main Injector. We have completed the first physics run in 2014 and continue collecting high statistic data samples of p+p, p+d, p+C, p+Fe and p+W collisions. E906 measures J/Psi, Psi’ and Drell-Yan yeilds in the dimuon channel over a wide range of kinematic coverages, which is optimal for studying light flavor asymmetry and quark energy loss effects in Drell-Yan. E906 has successfully reconstructed the dimuon mass spectrum with clear J/Psi and Psi' signals from the latest 2014 data. We expect the results will shed new light on our understanding of the nucleon structure and the nature of quark energy loss in nuclear medium in p+A collisions. In this talk, we will discuss the current status and preliminary results.
