Title:The decays of exotic hadrons in the molecular scenario

Speaker: Dr. Yin Huang

Host:Prof. Lisheng Geng

Abstract:

The decays and production of hadrons is very important in deciphering their internal structure and understanding the non-perturbative QCD. We take the mass of the exotic state as inputs, and calculate the decay width using the compositeness condition method and triangulation method with the help of effective Lagrangians. By comparison with the experimental observation, the current results of the total decay widths support the newly discovered Omega_c(3119) or Omega_c(3050) as DXi molecules and Sigma_b(6227) as a K-barSigma_b molecule.
