Abstract

Spectra and correlations from RHIC are analyzed to determine the phase space density and total entropy. The phase space density for pions is higher and the entropy is thus lower than some expectations, but there seems to be enough entropy carried by other species, especially baryons, to roughly match the total entropy expected from lattice gauge calculations.
RHIC的熵和相空间密度
分析了RHIC的光谱和相关关系,确定了相空间密度和总熵。介子的相空间密度更高,因此熵低于一些预期,但其他物质,特别是重子,似乎携带了足够的熵,大致符合晶格规范计算所期望的总熵。
