STAR净电荷喷流关联的第一个结果

First Result of Net-Charge Jet-Correlations from STAR

Quan Wang

摘要:

我们给出了高$p_T$触发粒子的净电荷的方位角关联的结果。发现净电荷关联形状与总电荷关联形状相似。在近侧,净电荷和总电荷$p_T$谱具有相似的形状,并且都比夹杂物硬。在远离侧,相关光谱并不比内含物硬得多,并且净电荷/总电荷比随着$p_T$而增加,并且与内含物比相似。

英文摘要:

We presented results on azimuthal correlation of net-charge with high $p_T$ trigger particles. It is found that the net-charge correlation shape is similar to that of total-charge. On the near-side, the net-charge and total-charge $p_T$ spectra have similar shape and both are harder than the inclusives. On the away-side, the correlated spectra are not much harder than the inclusives, and the net-charge/total-charge ratio increases with $p_T$ and is similar to the inclusive ratio.
