论文摘要
在相对论重离子碰撞器（RHIC）（RHIC）以及中央和外围铅（pb-pb）和PP $ collions（by Pp $ collions collions collions coldrions coldrions coldrions coldrions）（lhc）（lhc）（lhc collies）（lhc collies）（lhc）（lhc），在中央和外围金金（Au-au）中产生的不同类型颗粒的横向动量光谱以及（$ pp $）碰撞（$ pp $）碰撞（lhc）多组件。从标准分布中获得的结果给出了与Star，Phenix和Alice合作的测量实验数据的近似协议。获得了有效（动力学冻结）温度，横向流速和动力学冻结体积的有条不紊的行为，并获得了对不同颗粒的质量依赖性，这观察到与较轻的颗粒相比，早期的动力学冻结较重颗粒的早期冻结。观察到不同颗粒的排放的参数是不同的，这揭示了质量依赖差异动力学冻结的直接特征。还观察到，在每个核子对的同一质量中心能量上，外围核核核（$ aa $）和$ pp $碰撞就提取的参数而言是接近的。
The transverse momentum spectra of different types of particles produced in central and peripheral gold-gold (Au-Au) and (inelastic) proton-proton ($pp$) collisions at the Relativistic Heavy Ion Collider (RHIC), as well as in central and peripheral lead-lead (Pb-Pb) and $pp$ collisions at the Large Hadron Collider (LHC) are analyzed by the standard distribution in terms of multi-component. The obtained results from the standard distribution give an approximate agreement with the measured experimental data by the STAR, PHENIX and ALICE Collaborations. The methodical behavior of the effective (kinetic freeze-out) temperature, transverse flow velocity and kinetic freeze-out volume with the mass dependence for different particles is obtained, which observes the early kinetic freeze-out of heavier particles as compared to the lighter particles. The parameters for emissions of different particles are observed to be different, which reveals a direct signature of the mass dependent differential kinetic freeze-out. It is also observed that the peripheral nucleus-nucleus ($AA$) and $pp$ collisions at the same center-of-mass energy per nucleon pair are close in terms of the extracted parameters.
