| Outline of Final Research Achievements |
The Drell-Yan process from proton+proton and proton+deuteron reactions was measured using proton beam and liquid hydrogen/deuterium targets at Fermilab in USA. It is aimed at deriving the asymmetry and the absolute amounts of anti-up and anti-down quarks in the proton. Physics data were accumulated in three data-taking periods from H25/11 to H28/07 (planned), and in the first period a detector for absolute beam intensity was developed and installed. The physics data were analyzed and a preliminary result of the asymmetry of anti-up and anti-down quarks was obtained.
