Abstract :
It is shown that the absolute rate of the semileptonic decays of the ≡c baryons can be as much as two times higher than the semileptonic decay rate of Λc due to the Pauli interference of the strange quark. This interference effect is still larger in the semileptonic decay rate of 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.
