我们进行了可行性研究的各种单横向自旋测量，与西弗斯效应，横向和张量收费，和柯林斯碎裂功能。研究的过程包括半包容性的深非弹性散射（SIDIS），其中除了散射的DIS轻子外，还检测到单个强子（π介子和K介子）。这些数据是在使用ECCE探测器配置的Pythia 6和Pythia 4模拟的18 GeV对275 GeV，18对100，10对100和5对41的e+ p碰撞中获得的。选择了典型的DIS运动学，最值得注意的是Q 2> 1 GeV 2，并且覆盖了从1 0− 4到1的x范围。单自旋不对称性被提取为x和Q2的函数，以及半包含变量z，其对应于检测到的强子相对于撞击的部分子携带的动量分数，以及PT，其对应于检测到的强子相对于虚光子的横向动量。它们是在强子横动量和核子横自旋相对于轻子散射平面的方位角的组合中的方位矩中得到的。为了提取不对称性，最初未极化的蒙特卡洛重新加权真实的运动学变量，强子类型和部分子口味的基础上固定目标SIDIS实验和e+ e−湮没数据的全局拟合。这种测量的预期统计精度外推到10 fb− 1，潜在的系统不确定性近似给出了真实和重建产量之间的偏差。通过将ECCE e+ p伪数据与EIC黄色报告中的相同数据进行比较，并相应地缩放相应的黄色报告e+ 3 He伪数据不确定性，可以获得类似的中子信息。对知识的西弗斯功能，横向和张量收费，和柯林斯功能的影响，然后在相同的唯象提取在黄色报告进行了评估。的影响被认为是与参数化的黄色报告探测器获得的，并表明ECCE探测器配置可以满足这些数量的物理目标。

We performed feasibility studies for various single transverse spin measurements that are related to the Sivers effect, transversity and the tensor charge, and the Collins fragmentation function. The processes studied include semi-inclusive deep inelastic scattering (SIDIS) where single hadrons (pions and kaons) were detected in addition to the scattered DIS lepton. The data were obtained in pythia 6 and geant 4 simulated e+ p collisions at 18 GeV on 275 GeV, 18 on 100, 10 on 100, and 5 on 41 that use the ECCE detector configuration. Typical DIS kinematics were selected, most notably Q 2> 1 GeV 2, and cover the x range from 1 0− 4 to 1. The single spin asymmetries were extracted as a function of x and Q 2, as well as the semi-inclusive variables z, which corresponds to the momentum fraction the detected hadron carries relative to the struck parton, and P T, which corresponds to the transverse momentum of the detected hadron relative to the virtual photon. They are obtained in azimuthal moments in combinations of the azimuthal angles of the hadron transverse momentum and transverse spin of the nucleon relative to the lepton scattering plane. In order to extract asymmetries, the initially unpolarized MonteCarlo was re-weighted in the true kinematic variables, hadron types and parton flavors based on global fits of fixed target SIDIS experiments and e+ e− annihilation data. The expected statistical precision of such measurements is extrapolated to 10 fb− 1 and potential systematic uncertainties are approximated given the deviations between true and reconstructed yields. Similar neutron information is obtained by comparing the ECCE e+ p pseudo-data with the same from the EIC Yellow Report and scaling the corresponding Yellow Report e+ 3 He pseudo-data uncertainties accordingly. The impact on the knowledge of the Sivers functions, transversity and tensor charges, and the Collins function has then been evaluated in the same phenomenological extractions as in the Yellow Report. The impact is found to be comparable to that obtained with the parametrized Yellow Report detector and shows that the ECCE detector configuration can fulfill the physics goals on these quantities.
