Pb-Pb、p-Pb和p-p碰撞中涨落弦的纵向关联
Longitudinal correlations from fluctuating strings in Pb-Pb, p-Pb, and p-p collisions
摘要：
在一个具有纵向延伸的波动端点弦的半解析模型框架下，我们证明了在大型强子对撞机能量下Pb-Pb，p-Pb和p-p碰撞中的快度谱和两粒子关联可以普遍再现.在我们的方法中，字符串被拉受伤的成分出现在Glauber建模在部分音水平。从弦的强子发射得到的快度轮廓产生的终点波动的分布范围。然后，可以得到赝快度中两粒子关联的极限。我们的结果是有利的比较，最近的实验数据从ATLAS协作。
英文摘要：
In a framework of a semi-analytic model with longitudinally extended strings of fluctuating end-points, we demonstrate that the rapidity spectra and two-particle correlations in collisions of Pb-Pb, p-Pb, and p-p at the energies of the Large Hadron Collider can be universally reproduced. In our approach, the strings are pulled by wounded constituents appearing in the Glauber modeling at the partonic level. The obtained rapidity profile for the emission of hadrons from a string yields bounds for the distributions of the end-point fluctuations. Then, limits for the two-particle-correlations in pseudorapidity can be obtained. Our results are favorably compared to recent experimental data from the ATLAS Collaboration.
