The future gold beams with energies of up to 3.8AGeV from the Nuclotron at JINR in Dubna are well suited to study the equation of state of dense baryonic matter, and to explore the microscopic degrees-of-freedom emerging at neutron star densities. The relevant observables in heavy-ion collisions at these energies include yield and multidifferential distributions of (multi-) strange particles, collective flow of identified particles, fluctuation of conserved quantities and hypernuclei. In order to measure these observables in Au + Au collisions with rates of up to 50kHz, the Baryonic Matter@Nuclotron setup will be upgraded with a highly granulated and fast hybrid tracking system, and a forward calorimeter for event plane determination. The physics program, the detector upgrades and physics performance studies will be presented.

NICA 升级的重子物质@nuclotron 实验中的重离子程序

能量高达3.8A的未来金光束来自杜布纳 JINR 核子加速器的 GeV 非常适合研究致密重子物质的状态方程，并探索在中子星密度下出现的微观自由度。在这些能量下的重离子碰撞中的相关观测包括（多）奇异粒子的产额和多微分分布、已识别粒子的集体流动、守恒量和超核的波动。为了测量 Au 中的这些可观测物+Au 碰撞率高达 50kHz，Baryonic Matter@Nuclotron 设置将升级为高度颗粒化和快速混合跟踪系统，以及用于事件平面确定的前向热量计。将介绍物理程序、探测器升级和物理性能研究。
