对撞机框架中的极化e-p弹性散射
Polarized e-p Elastic Scattering in the Collider Frame
摘要:
在对撞机运动学中考虑了双极化弹性e-p截面和非对称性。协变表达式推导出的一般情况下,涉及交叉光束,这些检查对众所周知的结果时,质子是在休息。结果给出了使用现代模型的质子电磁形状因子的运动学感兴趣的电子-p对撞机,如EIC设施,这是在其规划阶段。在上下文中,宇称违反弹性电子-p散射进行了比较和对比,这些双极化(宇称守恒)的结果。
英文摘要:
Double polarization elastic e-p cross sections and asymmetries are considered in collider kinematics. Covariant expressions are derived for the general situation involving crossed beams; these are checked against the well-known results obtained when the proton is at rest. Results are given using modern models for the proton electromagnetic form factors for kinematics of interest in e-p colliders such as the EIC facility which is in its planning stage. In context, parity-violating elastic e-p scattering is compared and contrasted with these double-polarization (parity-conserving) results.
