Title: The decays ofexotic hadrons in the molecular scenario

Speaker:  Dr.Yin Huang

Host: Prof. LishengGeng

Abstract:

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