Topological Diagram Analysis of Charmed Baryon Decays with Vector Mesons
Yixuan Wu, Fanrong Xu, Hai-Yang Cheng
In this work, we further develop the application of the topological diagram approach (TDA) to charmed baryon weak decays with a vector meson in th…
CP Violation in Hadronic Weak Decays of Charmed Baryons in the Topological Diagrammatic Approach
Hai-Yang Cheng, Fanrong Xu, Huiling Zhong
CP violation in the charmed baryon sector is generally expected to be very small, of order or even smaller. Nevertheless, large long-distance penguin topologies can be in…
Hadronic Weak Decays of Charmed Baryons in the Topological Diagrammatic Approach: An Update
Hai-Yang Cheng, Fanrong Xu, Huiling Zhong
There exist two distinct ways in realizing the approximate SU(3) flavor symmetry of QCD to describe the two-body nonleptonic decays of charmed baryons: the irreducible SU(3) approa…
Tetraquark nature of the meson in hadronic decays
Hai-Yang Cheng, Cheng-Wei Chiang, Fanrong Xu
The internal structure of the light scalar meson is explored in the three-body decays of through the intermediate state , where…
Analysis of Hadronic Weak Decays of Charmed Baryons in the Topological Diagrammatic Approach
Huiling Zhong, Fanrong Xu, Hai-Yang Cheng
We perform a global fit to the experimental data of two-body charmed baryon decays based on the topological diagrammatic approach (TDA) and take into account the phase shifts betwe…
