【 摘 要 】

We introduce an integrable impurity model, in which both the electrons and impurities have spin and flavor degrees of freedom. This model is a generalization of the multichannel Kondo model, and is closely related with resonant tunneling through a quantum dot. The Hamiltonian is exactly diagonalized by means of the Bethe ansatz.
