摘要：
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-+/- to p(+/-) mesons produced in pp collisions as a function of root s. A fast rise of this ratio, when the initial energy increases starting from the kaon production threshold up to root s similar or equal to 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.
