Baryon chiral perturbation theory with virtual photons and leptons
Nopmanee Supanam, Harold W. Fearing, Yupeng Yan
We construct the general pion-nucleon SU(2) Lagrangian including both virtual photons and leptons for relativistic baryon chiral perturbation theory up to fourth order. We include…
Dependence of nucleon properties on pseudoscalar meson masses
Amand Faessler, Thomas Gutsche, Valery E. Lyubovitskij +1
We discuss the sensitivity of nucleon properties (mass, magnetic moments and electromagnetic form factors) on the variation of the pseudoscalar meson masses in the context of the p…
Bottom Baryon Decays in Non-relativistic Quark Model
A. Limphirat, K. Khosonthongkee, C. Kobdaj +2
The reactions , , and are studied in the non-relativistic quark model with all the model parameters fixed in the sector of…
Electromagnetic form factors of the baryon octet in the perturbative chiral quark model
S. Cheedket, V. E. Lyubovitskij, Th. Gutsche +3
We apply the perturbative chiral quark model at one loop to analyze the electromagnetic form factors of the baryon octet. The analytic expressions for baryon form factors, which ar…
