The generalized quark distributions (GPDs) describing the 3-D structure of kaon in light-cone quark model are investigated. We use the longitudinal momentum transfer to be zero for the analyses. The dependence of GPDs with respect to the quark longitudinal momentum fraction x and total momentum ...
We address an actual problem of baryon-resonance dominated meson-exchange processes in the low GeV regime, i.e. the phase and the structure of meson-NN* transition vertices. Our starting point is a quark-diquark model for the baryons (obeying approximate covariance; the mesons are kept as ...
The structure function of the constituent quark/antiquark can be extracted from the Kaon (pion) structure function, P(x), assuming that the asymptotic fo... Luis Trevisan,Carlos Tarrillo,L Tomio,... 被引量: 0发表: 2022年 The quarkonia-glueball structure of η, η′ and η(1410) ...
We study the kaon nuclear optical potential including the effect of the \Theta^+ pentaquark in a self-consistent approach, starting from an extension of the Juelich meson-exchange potential as bare kaon-nucleon interaction. Significant differences between a fully self-consistent calculation and the ...
In this talk we present our recent studies for the unpolarized fragmentation functions for the pion and kaon, employing the nonlocal chiral quark model, which manifests the nonlocal interaction between the quarks and pseudoscalar mesons, in the light-cone frame. It turns out that the nonlocal ...
We study the internal structure of a range of four-quark states with charm quark contributions using a two-body Bethe–Salpeter equation. Thereby, we

In this manner, the properties of elastic resonances such as the f0(500) and the ρ(770) in pion–pion as well as the K0∗(700) and K∗(892) in pion–kaon scattering have been investigated with respect to their quark-mass dependence [10, 11]. Nevertheless, by far not all ...
