NA61/SHINE在CERN SPS能区观测到的核-核碰撞的涨落和关联

Fluctuations and correlations in nucleus-nucleus collisions observed by NA61/SHINE at CERN SPS energies

Maja Maćkowiak-Pawłowska

摘要:

NA61/SHINE强相互作用计划旨在探索强相互作用物质的相图。主要物理目标是研究强相互作用物质的临界点和解除禁闭的开始。通过对束流动量(13A-158AGeV/c)和碰撞系统(p + p,p + Pb,Be + Be,Ar + Sc,Nd + La,Pb + Pb)尺寸的扫描,实现了上述目标。这一贡献提出了新的结果,系统的大小和能量依赖的多重性和净电荷波动测量这些分布的高阶矩。此外,还讨论了基于Levy源的核-核碰撞中玻色-爱因斯坦关联测量的新结果以及13AGeV/c的Pb + Pb相互作用中各向异性流的新进展。

英文摘要:

The NA61/SHINE strong interaction programme aims to explore the phase diagram of the strongly interacting matter. The main physics goals are the study of the onset of deconfinement and the search for the critical point of the strongly interacting matter. These goals are pursued by performing a scan in beam momentum (13A -- 158A GeV/c) and size of colliding system (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La, Pb+Pb). This contribution presents new results on system size and energy dependence of multiplicity and net-charge fluctuations measured with higher-order moments of these distributions. Also, new results on the measurement of Bose-Einstein correlations in nucleus-nucleus collisions based on Levy sources are discussed as well as news on anisotropic flow in Pb+Pb interactions at 13A GeV/c.
