Electron-Positron to Nucleon-Antinucleon Pair at Threshold and Proton Form Factor

Y. Yan, K. Khosonthongkee, C. Kobdaj +1

The reactions of electron-positron to nucleon-antinucleon pair at energy threshold are studied in a non-perturbative quark model. The puzzling experimental result that the ratio of…

Bottom Baryon Decays in Non-relativistic Quark Model

A. Limphirat, K. Khosonthongkee, C. Kobdaj +2

The reactions $Σ_{b}^{*} \to Λ_{b} π$ , $Σ_{b} \to Λ_{b} π$ , and $Ξ_{b}^{*} \to Ξ_{b} π$ are studied in the $^{3} P_{0}$ non-relativistic quark model with all the model parameters fixed in the sector of…

Axial form factor of the nucleon in the perturbative chiral quark model

K. Khosonthongkee, V. E. Lyubovitskij, Th. Gutsche +4

We apply the perturbative chiral quark model (PCQM) at one loop to analyze the axial form factor of the nucleon. This chiral quark model is based on an effective Lagrangian, where…
