强子形成与QCD物质的Phase Diagram

Hadron Formation and the Phase Diagram of QCD Matter

Reinhard Stock, Francesco Becattini, Thorsten Kollegger, Michael Mitrovski, Tim Schuster

摘要:

我们调查强子种冻结出系统学在A+A碰撞在低SPS能量,对应于一个以上的300 MeV的重化学势,分析NA49强子生产数据的统计强子化模型的框架内,并在UrQMD强子输运模型。在没有偏离普适巨正则强子化学平衡冻结的情况下,我们认为所观测到的强子冻结点应该普适地标志着QCD物质相图中强子相的边界线。

英文摘要:

We investigate hadronic species freeze-out systematics in A+A collisions at low SPS energies, corresponding to a baryochemical potential above 300 MeV, analyzing NA49 hadron production data in the framework of the statistical hadronization model, and in the UrQMD hadronic transport model. Observing no deviation from universal grand canonical hadro-chemical equilibrium freeze-out, we argue that the observed hadronic freeze-out points should universally signal the boundary line of the hadronic phase in the QCD matter phase diagram.
