Query: Ground State Mass Predictions of Heavy-Light Hybrids from QCD Sum-Rule
  Analysis ($J^P=\left\{0^{\pm},\,1^{\pm}\right\}$)   We present QCD Laplace sum-rule predictions of ground state masses of
heavy-light open-flavour hybrid mesons. Having computed leading-order diagonal
correlation functions, including up to dimension six gluon condensate
contributions, we extract hybrid mass predictions for all $J^P \in \{0^\pm,
1^\pm\}$, and explore possible mixing effects with conventional meson states.
Similarities are found in the mass hierarchy in both charm and bottom systems
with some exceptions that are discussed.
