Two-photon Exchange Corrections to Single Spin Asymmetry of Neutron and He
Dian-Yong Chen, Yu-Bing Dong
In a simple hadronic model, the two-photon exchange contributions to the single spin asymmetries for the nucleon and the He are estimated. The results show that the elastic con…
Strong two-body decays of the Lambdac(2940)+ in a hadronic molecule picture
Yubing Dong, Amand Faessler, Thomas Gutsche +1
The Lambdac(2940)+ baryon with possible quantum numbers J(P) = 1/2+ and 1/2- is studied as a molecular state composed of a nucleon and D* meson. We give predictions for the strong…
J/psi gamma and psi(2S) gamma decay modes of the X(3872)
Yubing Dong, Amand Faessler, Thomas Gutsche +1
The X(3872) with quantum numbers J(PC) = 1(++) is considered as a composite state containing both molecular hadronic and a c bar(c) component. Based on this structure assumption we…
Nucleon Form Factors in a Light-Cone Quark Model with Two-Photon Exchange
Dian-Yong Chen, Yu-Bing Dong
We estimate the two-photon exchange corrections to both proton and neutron electromagnetic physical observables in a relativistic light cone quark model. At a fixed momentum transf…
Form factors in RQM approaches: constraints from space-time translations, extension to constituents with spin-1/2 and unequal masses
Bertrand Desplanques, Yu-Bing Dong
Constraints related to transformations of currents under space-time translations have been considered for the relativistic quantum mechanics calculation of form factors of J=0 syst…
contribution in at small
Hai Qing Zhou, Dian Yong Chen, Yu Bing Dong
Two-photon annihilate contributions in the process including and intermediate are discussed in a simple hadronic model. The corrections to the u…
