Mixing-angle sensitivity of inclusive and lifetimes
Hai-Yang Cheng, Chia-Wei Liu, Fanrong Xu
We study the inclusive lifetimes of , , and , with emphasis on the mixing between the spin-zero and spin-one -diquark configurations. The re…
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…
Topological Diagrams and Hadronic Weak Decays of Charmed Baryons
Huiling Zhong, Fanrong Xu, Hai-Yang Cheng
Inspired by the recent BESIII measurement of the decay asymmetry and the phase shift between - and -wave amplitudes in the decay , we perform a global fit to…
