论文摘要
在自相似性方法中介绍了$ pp $碰撞产生的作为其横向动量$ p_t $的功能作为其横向动量$ p_t $的功能的同变动量$ p_t $的功能的计算。提出了对广泛的初始能量范围内数据的令人满意的描述。我们主要关注$ k^\ pm $与$ pp $ collisions生产的跨截面的比率，这是$ \ sqrt {s} $的函数。当初始能量从KAON的生产阈值开始到$ \ sqrt {s} \ simeq $ 20-30 GEV时，该比率的快速上升均与其非常慢的LHC能量一起揭示。该比率的能量依赖性归因于四摩梅塔的保护定律以及初始和产生的hadron的量子数，以及在大能量下的横截面行为。这些比率与Na61-shine，RHIC和LHC数据的令人满意的一致性或多或少。
A calculation of the inclusive spectra of pions and kaons produced in $pp$ collisions as functions of their transverse momentum $p_t$ at mid-rapidity is presented within the self-similarity approach. A satisfactory description of the data within a wide range of initial energies is presented. We focus mainly on the ratio of cross-sections of $K^\pm$ to $π^\pm$ mesons produced in $pp$ collisions as a function of $\sqrt{s}$. A fast rise of this ratio, when the initial energy increases starting from the kaon production threshold up to $\sqrt{s}\simeq$ 20-30 Gev, is revealed together with its very slow increase up to LHC energies. The energy dependence of this ratio is due to the conservation laws of four-momenta and quantum numbers of the initial and produced hadrons, and to the Regge behavior of cross-sections at large energies. The more or less satisfactory agreement of these ratios with NA61-SHINE, RHIC and LHC data is demonstrated.
