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 wi…
SPARSE: Scattering Poles and Amplitudes from Radial Schrödinger Equations
Roberto Bruschini
We introduce an algorithm for the solution of a system of radial Schrödinger equations describing the inelastic scattering of particles with spin in a partial wave with definite t…
Hidden-Heavy Pentaquarks and Where to Find Them
Fareed Alasiri, Eric Braaten, Roberto Bruschini
We provide a simple explanation for the observed hidden-charm pentaquarks as bound states in Born-Oppenheimer potentials. We identify , …
The Pattern of Exotic Hidden-Heavy Hadrons Revealed
Roberto Bruschini
For more than twenty years, theory has failed to explain the pattern of the exotic heavy hadrons. We illustrate a simple solution to this longstanding puzzle using the Born-Oppenhe…
Exotic Hidden-heavy Hadrons and Where to Find Them
Eric Braaten, Roberto Bruschini
The Born-Oppenheimer potentials for QCD with light quarks include adjoint-hadron potentials that are repulsive at short distances and heavy-hadron-pair potentials that approach thr…
