质子弹性散射的自旋不对称性和Pomeron的自旋相关耦合

Spin asymmetries for elastic proton scattering and the spin dependent couplings of the Pomeron

T. L. Trueman

摘要:

本文是RHIC极化质子计划中所做的大量分析报告。这包括在碰撞束或固定目标模式下质子对质子的弹性散射数据以及质子束对碳目标的弹性散射数据。除了提供一个模型的能量依赖性的质子极化所需的弹性散射的分析能力,它也提供了一些重要的信息,自旋依赖性的主导Regge极点。最值得注意的是,数据表明Pomeron具有显著的自旋翻转耦合。这使得双自旋翻转不对称性A_{NN}的探索,其中一些数据在很宽的能量范围内,现在是可用的,随着一个具体实现的建议Odderon搜索。

英文摘要:

This paper serves as a report on the large amount of analysis done in conjunction with the polarized proton program at RHIC. This comprises elastic scattering data of protons on protons in colliding beam or fixed target mode and proton beams on carbon targets. In addition to providing a model for the energy dependence of the analyzing power of elastic scattering needed for proton polarimetry, it also provides some significant information about the spin dependence of dominant Regge poles. Most notably, the data indicates that the Pomeron has a significant spin-flip coupling. This allows the exploration of the double spin flip asymmetry A_{NN} for which some data over a wide energy range is now available, along with a concrete realization of a proposed Odderon search.
