论文摘要
使用HYQ(2+1)的HOTQCD协作的高统计数据集 - 对轻巧和奇怪的夸克进行了使用,并在淬灭近似中处理魅力部门,我们分析了Charm波动的第二和第四阶累积累积累积,并与Charm与较轻的风味量子量子量相呼应。我们可以利用因$ {N_τ= 8} $ lattices的一个因子100较大的统计数据,该量子从未用于魅力波动的研究。分析魅力波动与重子数量和电荷波动的相关性,我们可以投射到Charmed Baryon和Meson相关性上,并将结果与Quark模型扩展的HADRON共振气体模型计算进行比较。我们的目的是精确地确定诱人的hadron的解离温度,并将探测波动的灵敏度可观察到的对多链式重子的存在。
Using the high statistics datasets of the HotQCD Collaboration, generated with the HISQ (2+1)-flavor action for light and strange quarks, and treating the charm sector in the quenched approximation, we analyze the second and fourth order cumulants of charm fluctuations and the correlations of charm with lighter conserved flavor quantum numbers. We can make use of a factor 100 larger statistics on ${N_τ=8}$ lattices which never have been used in studies of charm fluctuations. Analyzing correlations of charm fluctuations with baryon number and electric charge fluctuations we can project onto charmed baryon and meson correlations and compare results with quark model extended hadron resonance gas model calculations. We aim at a precise determination of the dissociation temperature of charmed hadrons and will probe the sensitivity of the fluctuations observables to the presence of multiple-charmed baryons.
