STAR中奇异粒子的高pT关联
High pT correlations with strange particles in STAR
摘要：
本文介绍了当前已发现的奇异粒子DeltaPhi和DeltaEta关联分析的主要内容，包括喷流和脊的系统尺寸和散射pT，喷流、脊和远离侧的介子/重子比，以及多奇异重子关联分析的现状。我们看到所有奇异重子和K 0短介子的强度相当的清晰的方位角峰。我们没有看到可观察到的物种依赖于同侧射流或脊产量作为pT的函数。然而，当远离侧和脊具有与本体相似的λ与K 0短比时，仅喷流比与$p+p$中的相似。这些研究结果对当前介质中射流理论解释的影响进行了讨论。
英文摘要：
We present the highlights of the current identified strange particles DeltaPhi and DeltaEta correlations analyses, including system-size and trigger-pT of the jet and ridge, jet, ridge and away-side meson/baryon ratios, and the current state of the multi-strange baryon analysis. We see clear azimuthal peaks of comparable strength for all strange baryons and K0-short mesons. We see no observable species dependence on the same-side jet or ridge yields as a function of pT. However, while the away side and the ridge have Lambda to K0-short ratio similar to that of the bulk, the jet-only ratio is similar to that in $p+p$. The implications of these findings on current in-medium jet theoretical explanations are discussed.
