摘要

这项工作致力于在联合核研究所（JINR, Dubna）实施的重子物质在Nuclotron （BM@N）实验中碰撞后寻找\(\phi \)（1020）。为了分析重建算法的有效性，利用蒙特卡罗模拟了3.9 AGeV Xe光束与CsI目标的碰撞。通过对事件的重建和候选对的选择，得到了不变质量的分布，并确定了一个对应于\(\phi \)（1020）的峰。推导了奇异粒子的重构效率与速度和横向动量的关系。

Analysis of Reconstruction Efficiency of ϕ(1020) for the BM@N Experiment Using Monte Carlo Generated Events

This work is devoted to the search for \(\phi \)(1020) after collisions in the Baryonic Matter at Nuclotron (BM@N) experiment, implemented at the Joint Institute for Nuclear Research (JINR, Dubna). To analyze the effectiveness of the reconstruction algorithms, Monte Carlo simulations of the collision of a 3.9 AGeV Xe beam with a CsI target were used. After reconstruction of the events and selection of candidate pairs, distribution of the invariant mass was obtained and a peak corresponding to \(\phi \)(1020) was identified. The dependence of the reconstruction efficiency of the strange particle on rapidity and transverse momentum was derived.
