本文介绍了在5× 41GeV2和18× 275GeV2的轻子和强子束流组合下，用ECCE探测器设计方案测量质子深度非弹性散射中产生的电荷分离π介子和K介子的双自旋不对称性的评价。该研究使用非偏振模拟数据，通过完整的GEANT模拟探测器进行处理。这些数据，然后重新加权的部分子水平与DSSV螺旋度分布和DSS碎裂功能，以产生相关的不对称性，随后进行了分析。所进行的分析表明，ECCE检测器的概念提供了分辨率和接受度，在运动相空间中具有广泛的覆盖范围，需要一个强大的不对称提取。这反过来又允许精确提取海夸克螺旋度分布。
The evaluation of the measurement of double-spin asymmetries for charge-separated pions and kaons produced in deep-inelastic scattering from the proton using the ECCE detector design concept is presented, for the combinations of lepton and hadron beam energies of 5× 41 GeV 2 and 18× 275 GeV 2. The study uses unpolarised simulated data that are processed through a full GEANT simulation of the detector. These data are then reweighted at the parton level with DSSV helicity distributions and DSS fragmentation functions, in order to generate the relevant asymmetries, and subsequently analysed. The performed analysis shows that the ECCE detector concept provides the resolution and acceptance, with a broad coverage in kinematic phase space, needed for a robust extraction of asymmetries. This, in turn, allows for a precise extraction of sea-quark helicity distributions.
