Abstract

The future heavy-ion NICA collider (JINR, Dubna) will provide a variety of beam types with the range of collision energies from 4 to 11A GeV. New experimental data on event-by-event fluctuations and strangeness production allow addressing important QCD properties such as nature of deconfinement phase transition and the existence of the Critical End Point (CEP). Heavy-ion collisions at NICA will be measured with the multi-purpose detector—MPD, which provides precise reconstruction of multiple physics channels. NICA physics goals and the MPD concept are described with the emphasis on the detector performance in the study of the excitation function for high order moments of net-proton event-by-event multiplicity distributions. The results of a feasibility study for measuring at NICA spectra and yields of kaons and pions, and the strangeness-to-entropy ratio are presented as well.

NICA的MPD检测器研究逐事件波动和奇异性产生的前景

摘要

未来的重离子NICA对撞机（JINR，杜布纳）将提供具有4 A至11 A碰撞能量范围的多种光束类型GeV。关于逐事件波动和异常产生的新实验数据可以解决重要的QCD特性，例如解除约束相变的性质和临界终点（CEP）的存在。NICA上的重离子碰撞将通过多功能检测器MPD进行测量，该检测器可精确重建多个物理通道。在研究质子逐事件多重分布的高阶矩的激发函数时，重点介绍了检测器性能，从而描述了NICA物理目标和MPD概念。还介绍了在NICA光谱上测量钾离子和介子的产率以及奇异熵比的可行性研究结果。
