Determination of meson resonance contributions to pion and kaon inclusive spectra

π- and K-meson inclusive spectra with low transverse momenta in K-meson fragmentation region in Kp-interactions are determined on the basis of the assumption on a recombination mechanism of hadron production. It is shown that the pion and kaon spectra (both 'direct' and from resonance decay) in K-meson framgentation region can be expressed by structure functions of initial K-meson. Contributions from resonance decays from different meson multiplets (vector, axial and tensor) to pion and kaon inclusive spectra are determined. α=(3 AT/5 AV)=0.28±0.02 is found for the suppression factor of P-wave meson state production as compared to the S-wave one. It shown that with decreasing final meson mass the relative contribution of direct production to meson inclusive spectrum increases. In the limits of available experimental errors in meson resonance spectra there is found no dependence of meson yields on the value of summary spin of quark and antiquark producing meson (β=3 AP/AV=1). It is shown that analysis of meson resonance inclusive spectra allows one to determine not only the parameters of valence quark distribution in the initial K-meson but also the sea parton distributions. For the strange sea quark distribution in K-meson there is found SS(x)∝(1-x)nS) where nS=4.8±1.0, which agrees with the prediction of the quark counting rules for this quantity. (orig.)
