论文摘要
我们构建了一个相对论模型，以执行具有杜特隆靶标的电子和中微子散射实验中的独家，半独立和包含的非极化横截面以及各种极化可观察到的计算。强烈的相互作用动力学是由庞加莱群体的明确动态统一表示定义的，在该组中，相互作用和非相互作用表示中空间翻译和旋转的表示形式相同。 Argonne V18电位用于构建相对论的核子核子相互作用，该核子核子的相互作用再现了实验性杜特龙结合能和核子核子散射可观察到的。我们的形式主义不包括锥体生产通道，并忽略了电磁和弱核电流操作员的两体贡献。我们表明，它适用于运动学的过程，其中内部两核子的能量保持在斜杆生产阈值以下，但三摩梅特转移的幅度至少扩展到几个GEV。
We build a relativistic model to perform calculations of exclusive, semi-exclusive and inclusive unpolarized cross sections and various polarization observables in electron and neutrino scattering experiments with deuteron targets. The strong interaction dynamics is defined by an explicit dynamical unitary representation of the Poincaré group, where representations of space translations and rotations in the interacting and non-interacting representations are the same. The Argonne V18 potential is used to construct a relativistic nucleon-nucleon interaction reproducing the experimental deuteron binding energy and nucleon-nucleon scattering observables. Our formalism does not include the pion production channel and neglects two-body contributions in the electromagnetic as well as in the weak nuclear current operator. We show that it is applicable to processes at kinematics, where the internal two-nucleon energy remains below the pion production threshold but the magnitude of the three-momentum transfer extends at least to several GeV.
