Gluon distribution and mass decomposition of the pion and kaon

We present the gluon distribution functions of the pion and kaon in small- x and large- x regions, and compare them with the results obtained from lattice QCD and continuum Schwinger function methods. Whether in the small- x region or the large- x region, our gluon distribution of the pion is consis...

Summary:We present the gluon distribution functions of the pion and kaon in small- x and large- x regions, and compare them with the results obtained from lattice QCD and continuum Schwinger function methods. Whether in the small- x region or the large- x region, our gluon distribution of the pion is consistent with the results of lattice QCD and continuum Schwinger function methods. We also calculate the first four moments of gluon distributions of the pion and kaon at different Q 2 scales. In addition, we present the mass decomposition of the pion and kaon with the dynamical parton distribution functions calculated by the DGLAP equation with parton–parton recombination corrections. The mass structures of the pion and kaon are completely different from that of the proton.
