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…

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…
