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 \(\pi ^\pm \) 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. The more or less satisfactory agreement of these ratios with NA61/SHINE, RHIC and LHC data is demonstrated.

在自相似方法中，计算了在pp碰撞中产生的pion和kaon的包容谱，作为其在中间快速变化时其横向动量\（p_T \）的函数。给出了在广泛的初始能量范围内对数据的令人满意的描述。我们主要关注pp碰撞中产生的\（K ^ \ pm \）与\（\ pi ^ \ pm \）介子的横截面比率，作为\（\ sqrt {s} \）的函数。当初始能量从kaon生产阈值开始增加到\（\ sqrt {s} \ simeq \）时，该比率快速上升。揭示了20-30 GeV，以及直到LHC能量的非常缓慢的增加。该比率的能量依赖性是由于四动量的守恒定律以及初始和产生的强子的量子数所致。这些比例与NA61 / SHINE，RHIC和LHC数据或多或少地令人满意。
