论文摘要
$ \ sqrt {s _ {\ mathrm {nn}}} = $ 27和200 GEV的第一个测量值$ξ$和$ω$的定向流量和$ω$ collisions in au+au碰撞。合并总和规则与产生所有组成夸克的各种组合一起检查，例如$ k^{\！ $ \barλ（\ bar { $ \barΩ^{+}（\ bar {s} \ bar {s} \ bar {s}）$。对于这种组合，观察到对总和规则的系统违反，电荷的差异和组合的陌生内容差异。将测量值与具有电磁（EM）场的多相传输（AMPT）模型和Parton-Hadron String Dynamics（PHSD）模型的计算进行了比较。具有EM领域的PHSD模型与不确定性内的测量值一致。
The first measurements for rapidity-odd directed flow of $Ξ$ and $Ω$ in Au+Au collisions at $\sqrt{s_{\mathrm {NN}}}=$ 27 and 200 GeV are reported. The coalescence sum rule is examined with various combinations of hadrons where all constituent quarks are produced, such as $K^{\!^-}\!\!({ \bar{u}}{s})$, $\bar{p}({\bar{u}\bar{u}}{\bar{d}})$, $\barΛ(\bar{u}\bar{d}\bar{s})$, $ϕ({s}{\bar{s}})$, $\barΞ^{+}(\bar{d}\bar{s}\bar{s})$, $Ω^{-}(sss)$, and $\barΩ^{+}(\bar{s}\bar{s}\bar{s})$. For such combinations, a systematic violation of the sum rule is observed with increasing difference in the electric charge and the strangeness content of the combinations. Measurements are compared with the calculations of A Multi-Phase Transport (AMPT) model and Parton-Hadron String Dynamics (PHSD) model with electromagnetic (EM) field. The PHSD model with EM field agrees with the measurements within uncertainties.
