Symmetries of Excited Heavy Baryons In The Heavy Quark And Large N_c Limit
arXiv:hep-ph/9912385 · doi:10.1103/PhysRevLett.84.5474
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.
