The Xi(Q) - Xi-prime(Q) mixing and heavy baryon masses

We examine the {\sl\Xi}_Q-{\sl\Xi}'_Q mixing and heavy baryon masses in the heavy quark effective theory with the \mq corrections. In the conventional baryon assignment, we obtain the mixing angle

\cos ~2 \theta=0.87\pm 0.03

in virtue of the Gell-Mann

-

Okubo mass relation. On the other hand, if we adopt the new baryon assignment given by Falk, the allowed region of the {\sl\Sigma}_c mass is upper from 2372MeV.
