  Electron tunneling through a double quantum dot molecule side attached to a
quantum wire, in the Kondo regime, is studied. The mean-field finite-U
slave-boson formalism is used to obtain the solution of the problem. We found
conductance cancelations when the molecular energies of the side attached
double quantum-dot cross the Fermi energy. We investigate the many body
molecular Kondo states as a function of the parameters of the system.
