摘要
Abstract
The parton distribution functions of nucleons and mesons are basic physical quantities,while different research groups have got different results.With a very simple model that kaon is made up of only valence quarks at a low Q2 scale,the gluons and sea quarks are generated completely through the quantum chromodynamics (QCD) radiations.The modified dokshitzer-gribov-lipatov-altarelli-parisi (MD-DGLAP) equations is used as the QCD dynamical evolution equations.It is shown that the results can fit the experiments well.Compared the parton distributions and momentum distributions with the other models,the differences are obvious.We hope that future experiments can check them.关键词
