论文摘要
我们研究了在LHC进行的重离子碰撞中，重型离子碰撞的产量。我们假设它们是在夸克 - 胶原等离子体相结束时产生的，然后在强子气相期间与浅黑龙相互作用。我们使用合并模型来计算最初的多重性和有效的拉格朗日人来描述相互作用。我们发现，分子的初始多重性是两个比四夸克大的数量级。强子气体中的相互作用减少了分子的数量，并在每种情况下将四夸克人的数量增加一个因子。在动力学冻结时，差异仍然很大。
We study the production of heavy multiquark states in the heavy ion collisions performed at the LHC. We assume that they are produced at the end of the quark-gluon plasma phase and then interact with light hadrons during the hadron gas phase. We use the coalescence model to compute the initial multiplicities and effective Lagrangians to describe the interactions. We find that the initial multiplicity of molecules is two orders of magnitude larger than that of tetraquarks. The interactions in the hadron gas reduce the number of molecules and increase the number of tetraquarks by a factor two in each case. At kinetic freeze-out, the difference is still very large.
