چکیده
The sensitivity of W and Z production at RHIC to the possible ū/d̄ asymmetry in the proton is studied. The ratios of the W over W production cross sections in p+ p collision, as well as the ratios of the W and Z production cross sections for p + p over p + d collisions, are shown to be sensitive to this asymmetry. Predictions of various theoretical models for these ratios are presented. The validity of the Gottfried sum rule (GSR) [1], proposed more than 25 years ago, was recently tested by the New Muon Collaboration (NMC) in a muon deep inelastic scattering (DIS) experiment [2]. The Gottfried sum is given as

We study the d̄− ū asymmetry of the proton in a model approach in which hadronic fluctuations of the nucleon are generated through gluon splitting and recombination mechanisms. Within this framework, it is shown that the d̄ − ū asymmetry of the proton is consistently described by including only nucleon fluctuations to |πN〉 and |π∆〉 bound states. Predictions of the model closely agree with the rec...

We study the d̄ ū asymmetry of the proton in a model approach recently developed, in which hadronic fluctuations of the nucleon are generated through gluon splitting and recombination mechanisms. Within this framework, it is shown that both d̄/ū and d̄− ū distributions in the proton can be consistently described by including only nucleon fluctuations to |πN〉 and |π∆〉 bound states. Predictions of t...

The sensitivity of the spin dependence of high energy pp scattering, particularly the asymmetry A N N , to the odderon is demonstrated. Several possible ways of determining the spin dependence of the odderon coupling from small-t data are presented.
متن کاملPolarized light flavor sea–quark asymmetry in polarized semi–inclusive processes
We propose new formulas for extracting a difference of the polarized light sea–quark density, ∆d̄(x)−∆ū(x), from polarized deep–inelastic semi–inclusive data. We have estimated the value of it from the present experimental data measured by SMC and HERMES groups. Although the data might suggest a violation of polarized light flavor sea–quark symmetry, the precision of the present data is not enou...
متن کاملPhenomenological constraints on the flavour asymmetry of the nucleon sea
We study the possible flavour asymmetry, ū 6= d̄, of the light quark sea distributions of the proton. We discuss the information that is at present available from data on deep-inelastic lepton-nucleon scattering and from DrellYan production on various nuclear targets. We show that the ratio of dilepton yields on hydrogen and deuterium targets is very sensitive to ū − d̄. The increased precision o...
