脊是由定向射流传播和介质流动形成的吗?

Is the ridge formed by aligned jet propagation and medium flow?

Joshua Robert Konzer

摘要:

由于最近观察到脊随着触发粒子相对于事件平面的角度($ϕ_s$)而减小,因此理论上脊是由射流传播和介质流动之间的相互作用形成的。这种相互作用可能在固定的$ϕ_s$处产生脊方位角相关性的不对称性。我们提出了一个分析这种不对称性的STAR数据。我们发现在$ϕ_s\approx45^{\circ}$处有一个最大不对称的不对称脊,同时在所有$ϕ_s$处有一个对称喷流。

英文摘要:

Motivated by the recent observation that the ridge decreases with trigger particle angle ($ϕ_s$) relative to the event plane, it is theorized that the ridge is formed by interplay between jet propagation and medium flow. Such interplay may produce asymmetry in the ridge azimuthal correlation at a fixed $ϕ_s$. We present an analysis of this asymmetry from STAR data. We found an asymmetric ridge with maximum asymmetry at $ϕ_s\approx45^{\circ}$ concurrent with a symmetric jet at all $ϕ_s$.
