Flavor asymmetry of the nucleon sea and W-boson production

Research output: Contribution to journalArticlepeer-review


The advantage and feasibility of using W-boson production to extract unique information on the flavor asymmetry of the over(u, ̄) and over(d, ̄) sea-quark distributions in the proton are examined. The W+ and W- production cross section ratios in p + p collisions are shown to be sensitive to the over(d, ̄) / over(u, ̄) ratios, and they are free from charge-symmetry-breaking and nuclear-binding effects. The feasibility for measuring these ratios at the RHIC and LHC proton-proton colliders, as well as the expected sensitivity to the over(d, ̄) / over(u, ̄) ratios, are also presented.
