Meson-Meson Molecular Binding Potentials in the Diabatic Dynamical Diquark Model
Richard F. Lebed, Steven R. Martinez
Using the diabatic formalism, a rigorous generalization of the Born-Oppenheimer approximation, we study the effects of introducing simple meson-meson molecular potentials to an est…

in the Diabatic Diquark Model: Effects of Isospin
Richard F. Lebed, Steven R. Martinez
is an isoscalar 4-quark state with mass lying barely below the threshold, and several times further below the threshold. It allows both di-meso…

Diabatic Dynamical Diquark Bound States: Mass Corrections and Widths
Richard F. Lebed, Steven R. Martinez
Using the diabatic formalism, which generalizes the adiabatic approximation in the Born-Oppenheimer formalism, we apply well-known Hamiltonian methods to calculate the effect of op…
