标题： A Comparison between a Minijet Model and a Glasma Flux Tube Model for Central Au-Au Collisions at $\sqrt{s_{NN}}$=200 GeV

摘要： 在本文中，我们比较了两种模型在中心Au-Au碰撞下的情况，其中$\sqrt{s_{NN}}$=200 GeV。 第一个模型是一个小喷注模型，该模型假设大约产生$\sim$50个反向对的小喷注，并且具有改变的碎片函数。 还假设碎片是透明的并能逃逸出碰撞区域并被探测到。 第二个模型是一个胶子流管模型，该模型导致由火球中心附近相互作用的流管通过等离子体不稳定性驱动的径向膨胀火球表面的流管。 这个内部火球变成一个不透明的流体动力学流体，将表面流管向外推动。 大约$\sim$12个表面流管保留下来，并与$\sim$1/2产生的粒子碎片一起逃逸出碰撞区域并被探测到。 这两种模型都能再现不同$p_{t1}$ $p_{t2}$ bins中的两粒子角度相关性。 我们还比较了这两种模型的三个额外效应：介子重子比；称为脊的长程近侧相关性；以及应用于三粒子角度相关性时所谓的马赫锥效应。 显示英文摘要

摘要： In is paper we compare two models with central Au-Au collisions at $\sqrt{s_{NN}}$=200 GeV. The first model is a minijet model which assumes that around $\sim$50 minijets are produced in back-to-back pairs and have an altered fragmentation functions. It is also assumed that the fragments are transparent and escape the collision zone and are detected. The second model is a glasma flux tube model which leads to flux tubes on the surface of a radial expanding fireball driven by interacting flux tubes near the center of the fireball through plasma instabilities. This internal fireball becomes an opaque hydro fluid which pushes the surface flux tubes outward. Around $\sim$12 surface flux tubes remain and fragment with $\sim$1/2 the produced particles escaping the collision zone and are detected. Both models can reproduce two particle angular correlations in the different $p_{t1}$ $p_{t2}$ bins. We also compare the two models for three additional effects: meson baryon ratios; the long range nearside correlation called the ridge; and the so-called mach cone effect when applied to three particle angular correlations.
