Symmetries of Excited Heavy Baryons In The Heavy Quark And Large N_c Limit

TL;DR

This paper reveals a new contracted U(4) symmetry linking excited and ground state heavy baryons in the combined heavy quark and large N_c limit, providing a model-independent theoretical insight.

Contribution

It introduces a novel contracted U(4) symmetry in the combined heavy quark and large N_c limit, connecting excited and ground state heavy baryons.

Findings

Existence of a new contracted U(4) symmetry.

Symmetry connects orbitally excited and ground state heavy baryons.

Results are model independent.

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.
