DESCRIPTION:Speakers: Pan-Pan Shi (IFIC)\nWe reanalyze the lattice QCD dat
 a for the isoscalar $J^P=0^+$ and $1^+$ $\\bar b \\bar c u d$ systems at $
 m_{\\pi}\\simeq 220$ MeV by incorporating both short- and long-range inter
 actions. Using the interaction constrained by the lattice results\, we pre
 dict a spectrum of isoscalar $B^{(*)}\\bar D{}^{(*)}$ molecular states wit
 h quantum numbers $J^{P}=0^+$\, $1^+$\, and $2^+$. The predicted $J^P=0^+$
  and $1^+$ $B\\bar D$ and $B^*\\bar D$ bound states are consistent with th
 e lattice data. Moreover\, the two resonances reported by the lattice coll
 aboration in the $J^P=0^+$ and $1^+$ $\\bar b \\bar c u d$ channels are na
 turally interpreted as the $B^*\\bar D{}^{*}$ and $B\\bar D{}^{*}$ hadroni
 c molecules\, respectively. We further predict two previously unreported $
 B^*\\bar D{}^{*}$ states with quantum numbers $J^P=1^+$ and $2^+$\, corres
 ponding to a bound state and a virtual state\, respectively. Our results p
 rovide a unified interpretation of the lattice spectrum and highlight the 
 important interplay between short- and long-range interactions in the dyna
 mics of the $B^{(*)}\\bar D{}^{(*)}$ systems.\n\nhttps://indico.ific.uv.es
