在与宇称波动相关的RHIC观测到的角相关的其他贡献

Alternative Contributions to the Angular Correlations Observed at RHIC Associated with Parity Fluctuations

Scott Pratt

摘要:

最近在RHIC测量的角度相关的同号与相反的符号对已被解释为大尺度波动的宇称奇场的证据。在本文中,我们提供了不同的解释相同的现象的基础上,从电荷和动量守恒覆盖椭圆流的相关性。这些影响所示的相关性与测量的幅度相似。其他相关性也被考虑,但对其大小的估计表明它们是无关紧要的。

英文摘要:

Recent measurements at RHIC of angular correlations of same-sign vs. opposite sign pairs have been interpreted as evidence for large-scale fluctuations of parity-odd fields. In this paper, we provide alternative explanations of the same phenomena based on correlations from charge and momentum conservation overlaid with elliptic flow. These effects are shown to produce correlations with similar magnitudes as those measured. Other correlations are also considered, but estimates of their size suggest they are inconsequential.
