标题： HBT Correlators -- Current Formalism vs. Wigner Function Formulation

摘要： 我们澄清了Gyulassy、Kaufmann和Wilson开发的当前形式化方法与Pratt提出的2粒子关联函数的Wigner函数公式之间的关系。当应用于具有尖锐冻结超曲面的源的流体力学描述时，我们的结果消除了Makhlin和Sinyukov给出的处方中的一个轻微错误，该错误在文献中引起了混淆。 显示英文摘要

摘要： We clarify the relationship between the current formalism developed by Gyulassy, Kaufmann and Wilson and the Wigner function formulation suggested by Pratt for the 2-particle correlator in Hanbury-Brown Twiss interferometry. When applied to a hydrodynamical description of the source with a sharp freeze-out hypersurface, our results remove a slight error in the prescription given by Makhlin and Sinyukov which has led to confusion in the literature.
