论文摘要
我们使用3+1D准粒子各向异性流体动力学（AHYDROQP）来预测200 GEV和5.02 TEV重型离子碰撞中Kaon Hanbury-Brown-Twiss（HBT）Radii。使用先前确定的AHYDROQP参数，我们计算Kaonic HBT Radii及其比率作为对$ K_T $的平均横向动量的函数。我们首先考虑在200 GEV处的AU-AU碰撞，在AHYDROQP预测和实验数据之间找到良好的一致性，最高为$ k_t \ sim 0.8 $ GEV。然后，我们提出了关于Kaonic HBT半径及其在5.02 TEV PB-PB碰撞中的预测。我们的ahydroqp预测未显示出明显的$ k_t $缩放率和kaon源radii，但是，观察到近似的横向质量$ m_t $缩放率，尤其是在200 GEV时。
We use 3+1D quasiparticle anisotropic hydrodynamics (aHydroQP) to make predictions for kaon Hanbury-Brown-Twiss (HBT) radii in 200 GeV and 5.02 TeV heavy-ion collisions. Using previously determined aHydroQP parameters, we compute kaonic HBT radii and their ratios as a function of the mean transverse momentum of the pair $k_T$. We first consider Au-Au collisions at 200 GeV, finding good agreement between aHydroQP predictions and experimental data up to $k_T \sim 0.8$ GeV. We then present predictions for kaonic HBT radii and their ratios in 5.02 TeV Pb-Pb collisions. Our aHydroQP predictions do not exhibit a clear $k_T$ scaling of the pion and kaon source radii, however, an approximate transverse mass $m_T$ scaling is observed, particularly at 200 GeV.
