Description
Double-heavy hadrons can be identified as bound states in the Born-Oppenheimer potentials for QCD. We present parameterizations of the 5 lowest Born-Oppenheimer potentials from pure $SU(3)$ lattice gauge theory as functions of the separation $r$ of the static quark and antiquark sources. The parametrizations have the correct limiting behavior at small $r$, where the potentials form multiplets associated with gluelumps. They also have the correct limiting behavior at large $r$, where the potentials form multiplets associated with excitations of a relativistic string. These Born-Oppenheimer potentials can be used to develop models based on QCD for the many exotic heavy hadrons that have been discovered since 2003.
