论文摘要
最初提出，在重离子碰撞研究中使用电荷平衡功能是在这些碰撞中的延迟强调和两阶段夸克产生的探针。后来出现的是，一般平衡功能还可以作为光夸克的扩散性以及重离子碰撞中形成的系统的演变的探测。在这项工作中，我们重新审查了一般平衡函数的制定，并考虑如何最好地定义和测量这些相关函数，以不同于符号和类似粒子对的条件密度的差异。我们根据相关的粒子函数定义了一般平衡函数，并显示这些命令一个简单的总和规则。我们还继续区分表达为条件密度差异的平衡函数，无论实验接受界限和界限平衡功能是否有效，这些函数明确说明了实验的有限接受度。还扩展了一般平衡功能，以适应基于这些量子数的密度，可容纳奇怪的Baryon以及魅力和底部量子数。
The use of charge balance functions in heavy-ion collision studies was initially proposed as a probe of delayed hadronization and two-stage quark production in these collisions. It later emerged that general balance functions can also serve as a probe of the diffusivity of light quarks as well as the evolution of the systems formed in heavy-ion collisions. In this work, we reexamine the formulation of general balance functions and consider how to best define and measure these correlation functions in terms of differences of conditional densities of unlike-sign and like-sign particle pairs. We define general balance functions in terms of associated particle functions and show these obey a simple sum rule. We additionally proceed to distinguish between balance functions expressed as differences of conditional densities valid irrespective of experimental acceptance boundaries and bound balance functions that explicitly account for the limited acceptance of experiments. General balance functions are additionally extended to accommodate strange, baryon, as well as charm and bottom quantum numbers based on the densities of these quantum numbers.
