相对论性重离子碰撞中产生的超强子物质的化学性质

Chemical properties of super-hadronic matter created in relativistic heavy ion collisions

Scott Pratt, Claudia Ratti, William Patrick McCormack

摘要:

初步的电荷平衡功能,从星合作在相对论重离子对撞机(RHIC)进行比较,夸克产生的两个波的模型。如果一个化学平衡的夸克-胶子等离子体(QGP)被创造出来,那么第一波的强度和扩散范围应该由QGP的化学成分决定,而第二波应该由所观察到的末态强子所需的增加的夸克数量决定。一个简单的模型参数化的化学超强子物质和两个相关长度的两个波。计算结果与STAR协作的初步数据进行了比较。超强子物质的化学性质似乎在格点规范理论预期的20%以内。

英文摘要:

Preliminary charge balance functions from the STAR Collaboration at the Relativistic Heavy Ion Collider (RHIC) are compared to a model where quarks are produced in two waves. If a chemically equilibrated quark-gluon plasma (QGP) is created the strength and diffusive spread of the first wave should be governed by the chemical composition of the QGP, while the second wave should be determined by the increased number of quarks required to make the observed final-state hadrons. A simple model parameterizes the chemistry of the super-hadronic matter and the two correlation lengths for the two waves. Calculations are compared to preliminary data from the STAR Collaboration. The chemistry of the super-hadronic matter appears to be within 20\% of expectations from lattice gauge theory.
