title: Symmetries of excited heavy baryons in the heavy-quark and large- N(c) limit
abstract: We demonstrate in a model independent way that, in the combined heavy-quark and large- N(c) limit, there exists a new contracted U(4) symmetry which connects orbitally excited heavy baryons to the ground states.
