Color gauge invariant theory of diquark interactions
Jun-Feng Wang, De-Shun Zhang, Zhi-Feng Sun
In the present work, we construct a color gauge invariant theory of diquark interactions. With the transformation rule of the diquark fields and the definition of the covariant der…
Study on the structure of the state
Yan Ma, De-Shun Zhang, Cheng-Qun Pang +1
In this work, we studied the state within the framework of effective field theory. We firstly show the construction of the Lagrangian describing meson-meson-meson and…
The state considered as the mixture of hadronic molecule and diquark-antidiquark within effective field theory
De-Shun Zhang, Wei He, Chu-Wen Xiao +1
In the present work, we construct the Lagrangians including three-meson, meson-diquark-antidiquark vertices, such that the diquark-antidiquark component as well as the molecular co…
The states as the mixture of the molecular and diquark-anti-diquark components within the effective field theory
Wei He, De-Shun Zhang, Zhi-Feng Sun
In this study, we reconsider the states and by investigating the presence of diquark-anti-diquark components as well as the hadronic molecule components i…
