SMASH中重共振的影响

Influence of heavy resonances in SMASH

J. Salinas San Martin, J. Noronha-Hostler, H. Elfner, J. Hammelmann, R. Hirayama

摘要:

最近的格点量子色动力学结果表明,与强子共振气体模型相比,强子模型需要数百个粒子。这些额外的粒子影响状态方程和强子输运模型中的强子相互作用。在这里,我们介绍PDG21+粒子列表,其中包含最新的粒子及其属性数据库。然后,我们将所有粒子衰变转换为2体衰变,使它们与SMASH兼容,以产生更一致的描述重离子碰撞。

英文摘要:

Recent lattice QCD results, comparing to a hadron resonance gas model, have shown the need for hundreds of particles in hadronic models. These extra particles influence both the equation of state and hadronic interactions within hadron transport models. Here, we introduce the PDG21+ particle list, which contains the most up-to-date database of particles and their properties. We then convert all particles decays into 2 body decays so that they are compatible with SMASH in order to produce a more consistent description of a heavy-ion collision.
