论文摘要
据报道,在比约肯极限的非极化核上,对电子深度非弹性散射的严格光线形式。它保留了庞加莱协方差,宏观区域,包括颗粒数量和动量总和规则。该方案应用于A = 3 ISO-DOUBLET,鉴于计划的操作在电子离子对撞机处具有未偏振和极化的光束非常相关。与以前的轻率估计不同,我们的程序(包括现实的核描述和自由核电结构功能)预测欧洲的MUON合作效果相当可观,价格为$^3 $ HE。这将允许根据真正的QCD效应分析与拟议基线的偏差。较重的核的扩展很简单,尽管在数字上具有挑战性。
A rigorous light-front formalism for electron deep inelastic scattering on unpolarized nuclei, in Bjorken limit, is reported. It preserves Poincaré covariance, macroscopic locality, both number of particles and momentum sum rules. The scheme is applied to the A=3 iso-doublet, very relevant in view of the planned operation with unpolarized and polarized beams at the Electron-Ion Collider. At variance with previous light-front estimates, our procedure, including a realistic nuclear description and free-nucleon structure functions, predicts a sizeable European Muon Collaboration effect for $^3$He. This will allow to analyze deviations from the proposed baseline in terms of genuine QCD effects. The extension to heavier nuclei is straightforward, although numerically challenging.
