Abstract

The analysis of the reconstructed invariant \({{p}_{{\text{T}}}}\) spectra for the light hadrons (\({{\pi }^{ \pm }}\), \({{K}^{ \pm }}\), \(p\), and \(\bar {p}\)) is presented for simulated Bi + Bi collisions at \(\sqrt {{{s}_{{NN}}}} = 9.2\) GeV for the MPD detector. The obtained spectra have been fitted with thermal models. The rapidity densities and meson yields have been obtained. The improvement of low-\({{p}_{{\text{T}}}}\) energy loss correction is presented.

\(\sqrt {{{s}_{{NN}}}} = 9.2\) GeV模拟Bi + Bi碰撞中轻强子的pT光谱和速度分布分析

本文对MPD探测器在\(\sqrt {{{s}_{{NN}}}} = 9.2\) GeV模拟Bi + Bi碰撞的光强子（\({{\pi }^{ \pm }}\)、\({{K}^{ \pm }}\)、\(p\)和\(\bar {p}\)）重建不变\({{p}_{{\text{T}}}}\)光谱进行了分析。所得光谱已用热模型拟合。得到了快速密度和介子产额。提出了低\({{p}_{{\text{T}}}}\)能量损失校正的改进方法。

期刊介绍： The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
