Contributions to the nucleon form factors from bubble and tadpole diagrams
Z. Y. Gao, P. Wang, M. Y. Yang
The nonlocal chiral effective theory is applied to investigate the electromagnetic and strange form factors of nucleon. The bubble and tadpole diagrams are included in the calculat…
Sea quark contributions to the electromagnetic form factors of hyperons
Mingyang Yang, Ping Wang
We study the sea quark contributions to the electromagnetic form factors of baryons with nonlocal chiral effective theory. Both octet and decuplet intermediate states are inclu…
Electromagnetic form factors of octet baryons with the nonlocal chiral effective theory
Mingyang Yang, Ping Wang
The electromagnetic form factors of octet baryons are investigated with the nonlocal chiral effective theory. The nonlocal interaction generates both the regulator which makes the…
Hadronic cross section of annihilation at bottomonium energy region
Xiang-Kun Dong, Xiao-Hu Mo, Ping Wang +1
The Born cross section and dressed cross section of to and the total hadronic cross section in annihilation in the bottomonium energy region are calcul…
Sea quark contributions to nucleon electromagnetic form factors with the nonlocal chiral effective Lagrangian
Ming-Yang Yang, Ping Wang
The sea quark contributions to the nucleon electromagnetic form factors from up, down and strange quarks are studied with the nonlocal chiral effective Lagrangian. Both octet and d…
The opportunity to find in the decay
Chao-Yi Lü, Ping Wang, Yu-Bing Dong +2
was observed by WASA-at-COSY collaborations in the nuclear reaction recently. Its particularly narrow width may indicate the new QCD-allowed hadronic structure. To f…
Chiral extrapolation of nucleon axial charge in effective field theory
Hongna Li, Ping Wang
The extrapolation of nucleon axial charge is investigated within the framework of heavy baryon chiral effective field theory. The intermediate octet and decuplet baryons are…
Coulomb gauge model for hidden charm tetraquarks
W. Xie, L. Q. Mo, P. Wang +1
The spectrum of tetraquark states with hidden charm is studied within an effective QCD Coulomb gauge Hamiltonian approach. Of the four independent color schemes, two are investigat…
Coulomb gauge approach to scalar hadrons
Stephen R. Cotanch, Ignacio J. General, Ping Wang +1
The Coulomb gauge model, involving an effective QCD Hamiltonian in the Coulomb gauge, is applied to scalar hadrons. Mass predictions are presented for both conventional q-qbar meso…
Franck-Condon principle for heavy-quark hadron decays
Felipe J. Llanes-Estrada, Stephen R. Cotanch, Ignacio G. General +1
The Franck-Condon principle governing molecular electronic transitions is utilized to study heavy-quark hadron decays. This provides a direct assessment of the wavefunction of the…
Meson and tetra-quark mixing
Ping Wang, Stephen R. Cotanch, Ignacio J. General
The mixing between q-qbar meson and qqbar-qqbar tetra-quark states is examined within an effective QCD Coulomb gauge Hamiltonian model. Mixing matrix elements of the Hamiltonian ar…
Light 1-+ exotics: molecular resonances
Ignacio J. General, Ping Wang, Stephen R. Cotanch +1
Highlights in the search for nonconventional (non qqbar) meson states are the pi_1(1400) and pi_1(1600) exotic candidates. Should they exist, mounting theoretical arguments suggest…
