On the Mechanism of nucleon-nucleon Attraction by Pion Exchange
收藏 引用
Journal of Modern Physics 2018年 第8期9卷 1459-1468页
作者: Nicolae Bogdan Mandache Dragos Iustin Palade Plasma Physics and Nuclear Fusion Laboratory National Institute for Laser Plasma and Radiation Physics Bucharest-Magurele Romania
A formula is derived for the central nucleon-nucleon potential, based on an analysis of the physical origin of the nucleon-nucleon attraction by pion exchange. The decrease of the dynamical mass of the interaction fie... 详细信息

The 1/N_c Expansion in Hadron Effective Field Theory
收藏 引用
Communications in Theoretical Physics 2018年 第12期69卷 683-688页
作者: Guo-Ying Chen Department of Physics and Astronomy Hubei University of Education
We study the Nc scalings of pion-nucleon and nucleon-nucleon scatterings in hadron effective field *** assuming Witten's counting rules are applied to matrix elements or scattering amplitudes, which use the relativist... 详细信息

Dibaryon Signals in NN Scattering Data and Further Measurement at COSY,LEPS and CSR
收藏 引用
原子核物理评论 2009年 第S1期26卷 137-141页
作者: C. W. Wong Department of Physics and Astronomy University of California
The NΔ and ΔΔ dibaryon resonances are studied by calculating the NN scattering phase shifts with explicitly coupling these dibaryon channels in a multi-channel coupling calculation with two quark models. These quar... 详细信息

Two Pion versus σ-Meson Exchange Potentials
收藏 引用
Journal of Modern Physics 2015年 第7期6卷 927-936页
作者: Sachiko Oshima Takehisa Fujita Naohiro Kanda Akihiro Yoshimi College of Industrial Technology Nihon University Chiba Japan Department of Physics Faculty of Science and Technology Nihon University Tokyo Japan Research Core for Extreme Quantum World Okayama University Okayama Japan
The two pion exchange potentials are evaluated by carrying out the numerical integrations of three Feynman parameters in the corresponding Feynman diagrams. The two pion exchange potentials give rise to the attractive... 详细信息
