Abstract

It is shown that the absolute rate of the semileptonic decays of the Ξ_c baryons can be as much as two times higher than the semileptonic decay rate of Λ_c due to the Pauli interference of the strange quark. This interference effect is still larger in the semileptonic decay rate of Ω_c. An experimental measurement of the difference of these rates would thus provide an important piece of information on the spectator effects in decays of hadrons containing a heavy quark.
