利用最近从包含性质子和重离子深度非弹性散射(DIS)中提取的中子结构函数的再分析数据，我们重新检查了大部分子动量分数x时质子中d‘−u’不对称性形状的限制。对来自BCDMS、NMC、SLAC和Jefferson Lab DIS测量的质子-中子结构函数差异以及费米拉-Drell-yan轻子对产生截面的全局分析表明，对于目前可获得的所有x值，现有的数据可以用d‘>u’很好地描述。我们将拟合的d‘−u’分布的形状与基于手征对称破缺的非微扰模型的预期进行了比较，这可以通过即将到来的来自SeaQuest实验的较大x值的Drell-yan数据进行验证。
Using data from a recent reanalysis of neutron structure functions extracted from inclusive proton and deuteron deep-inelastic scattering (DIS), we re-examine the constraints on the shape of the d¯− u¯ asymmetry in the proton at large parton momentum fractions x. A global analysis of the proton–neutron structure function difference from BCDMS, NMC, SLAC and Jefferson Lab DIS measurements, and of Fermilab Drell-Yan lepton-pair production cross sections, suggests that existing data can be well described with d¯> u¯ for all values of x currently accessible. We compare the shape of the fitted d¯− u¯ distributions with expectations from nonperturbative models based on chiral symmetry breaking, which can be tested by upcoming Drell-Yan data from the SeaQuest experiment at larger values of x.
