论文摘要
我们介绍了CBM物理性能研究，以测量Net-Proton多重性分布的高阶累积物。这些可观察物是净 - 巴里果波动的替代，通常用于研究QCD相图的相结构。该模拟是针对$ au+au $ collision完成的，在梁动能$ e_ {lab} = 10 $ agev。横向动量范围$ 0.2 <p_t <2.0 $ gev/c，已计算出净 - 普罗顿分布的累积物（$ |Δy| = 1 $）。提出了Net-Proton的累积累积物的中心性依赖性，直到四个。使用展开技术校正效率和检测器效应。这项工作表明，可以使用CBM检测器测量Net-Proton的高阶累积物。
We present the CBM physics performance study for measurements of the higher order cumulants of the net-proton multiplicity distributions. These observables are proxy for net-baryon fluctuations and are commonly used to study the phase structure of QCD phase diagram. The simulation is done for $Au+Au$ collision at beam kinetic energy $E_{lab} = 10$ AGeV. The cumulants of net-proton distributions have been calculated at midrapidity ($|Δy| =1$) for the transverse momentum range $0.2 < p_T < 2.0$ GeV/c. The centrality dependence of cumulants of net-proton upto order four is presented. The efficiency and detector effects are corrected using unfolding techniques. This work shows that the higher order cumulants of net-proton can be measured using the CBM detector.
