The radiative decay of the axial-vector resonances into a pseudoscalar meson and a photon is studied using the vector meson Lagrangian obtained from the hidden gauge symmetry (HGS) formalism. The…
Three-body decay of Λc*(2595) and Λc*(2625) with the inclusion of a direct two-pion coupling

We investigate the three-body decays of $\Lambda_c^*(2595)$ and $\Lambda_c^*(2625)$ into $\Lambda_c \pi \pi$ by including a direct process going through the two-pion coupling of $\Lambda_c^*\Lambda_c…
Exotic hadrons with heavy flavors: X, Y, Z, and related states

We investigate the decays of the charmed baryons aiming at the systematic understanding of hadron internal structures based on the quark model by paying attention to heavy quark symmetry. We evaluate…
D -wave charmed and bottomed baryons from QCD sum rules

- 8 November 2016
We study the D-wave charmed baryons of SUd(3) flavor (3) over bar (F) using the method of QCD sum rules in the framework of heavy quark effective theory. We find that the Lambda(c)(2880),…
