Predicting $B^{(*)}\bar D{}^{(*)}$ states from a reanalysis of lattice QCD data

We reanalyze the lattice QCD data for the isoscalar $\bar b\bar c ud$ systems with $J^P=0^+$ and $1^+$ at $m_{\pi}\simeq 220$ MeV, incorporating both short- and long-range interactions constrained by heavy-quark spin and chiral symmetries. Using the interaction fitted to the lattice results, we predict a spectrum of is...
