未来电子-离子对撞机螺旋度部分子分布:定量评估

Helicity Parton Distributions at a Future Electron-Ion Collider: A Quantitative Appraisal

Elke C. Aschenauer, Rodolfo Sassot, Marco Stratmann

摘要:

我们提出了一个定量评估的影响,未来的电子-离子对撞机将有螺旋夸克和胶子密度的测定和质子自旋的贡献。我们的研究结果是通过执行一系列的全球QCD分析在次领先的顺序精度的基础上现实的伪数据集的包容性和半包容性的深度非弹性散射的纵向极化的电子和质子在不同的,可以想象的质心系统的能量。

英文摘要:

We present a quantitative assessment of the impact a future electron-ion collider will have on determinations of helicity quark and gluon densities and their contributions to the proton spin. Our results are obtained by performing a series of global QCD analyses at next-to-leading order accuracy based on realistic sets of pseudo-data for the inclusive and semi-inclusive deep-inelastic scattering of longitudinally polarized electrons and protons at different, conceivable center-of-mass system energies.
