Violation of the Gottfried sum rule was suggested by the New Muon Collaboration in
measuring proton and deuteron F2 structure functions. The finding triggered many …

Abstract The Drell–Yan massive lepton-pair production in hadronic collisions provides a
unique tool complementary to the Deep-Inelastic Scattering for probing the partonic …

Measurements of the ratio of Drell-Yan yields from an 800 GeV/c proton beam incident on
liquid hydrogen and deuterium targets are reported. Approximately 360 000 Drell-Yan muon …

Abstract The Drell-Yan cross section ratios, σ (p+ d)/σ (p+ p), measured in Fermilab E866,
have led to the first determination of d (x)/ū (x), d (x)− ū (x), and the integral of d (x)− ū (x) for …

A surprisingly large asymmetry between the up and down sea quark distributions in the
nucleon has been observed in recent deep inelastic scattering and Drell-Yan experiments …

▪ Abstract We review the production of high-mass lepton pairs in fixed-target experiments,
including both Drell-Yan (DY) and heavy quarkonium production [J/ψ, ψ′, ϒ (1 S), ϒ (2 S) …

A new QCD analysis of deep inelastic scattering (DIS) data is presented. All available
neutrino and antineutrino cross sections are reanalyzed and included in the fit, along with …

We review the current status and future prospects on the subject of flavor structure of the
nucleon sea. The flavor structure of the nucleon sea provides unique information on the non …

Evidence for a flavor asymmetry between the u¯ and d¯ quark distributions in the proton has
been found in deep-inelastic scattering and Drell-Yan experiments. The pronounced …

Sea quark distributions in the nucleon have naively been expected to be generated
perturbatively by gluon splitting. In this case, there is no reason for the light quark and anti …
