Hidden-heavy Pentaquarks in the Born-Oppenheimer Approximation for QCD
Fareed Alasiri, Eric Braaten, Roberto Bruschini
Hidden-heavy pentaquarks can be identified as bound states in diabatic Born-Oppenheimer potentials that are repulsive color-Coulomb potentials at short distance, cross below a heav…
Quarkoniumlike states above open-flavor thresholds in Born-Oppenheimer EFT
Nora Brambilla, Roberto Bruschini, Abhishek Mohapatra +2
Many quarkoniumlike states have been observed above open-flavor thresholds, but their organization and internal structure remain unsettled. We study the isoscalar hidden-charm and…
and its Partners in the Diabatic Born-Oppenheimer Approximation for QCD
Fareed Alasiri, Eric Braaten, Roberto Bruschini
In the Born-Oppenheimer approximation for QCD, the exotic hidden-charm tetraquark meson is a near-threshold bound state in Born-Oppenheimer potentials associated wit…
