论文摘要
横向动量分布的分析是了解高能碰撞中产生的相对论颗粒动力学的有用工具。找到适当的分布函数以近似光谱是粒子物理学研究的广泛发展领域。在这项工作中,我们对高能量物理学中统一的统计框架提供了详细的理论描述。我们通过分析了RHIC和LHC在重离子碰撞中产生的PION的横向动量光谱,测试了该框架对实验数据的适用性。我们还尝试解释使用统一统计框架在不同能量下在PP碰撞中形成的带电的Hadron的横向动量光谱。事实证明,这种形式主义可以很好地解释在软过程中产生的颗粒的光谱以及硬散射过程。
Analysis of transverse momentum distributions is a useful tool to understand the dynamics of relativistic particles produced in high energy collision. Finding a proper distribution function to approximate the spectra is a vastly developing area of research in particle physics. In this work, we have provided a detailed theoretical description of the unified statistical framework in high energy physics. We have tested the applicability of this framework on experimental data by analysing the transverse momentum spectra of pion produced in heavy-ion collision at RHIC and LHC. We have also attempted to explain the transverse momentum spectra of charged hadrons formed in pp collision at different energies using the unified statistical framework. This formalism has been proved to nicely explain the spectra of particles produced in soft processes as well hard scattering processes in a consistent manner.
