$T_{cc}$ in the Diabatic Diquark Model: Effects of $D^{*} D$ Isospin

Richard F. Lebed, Steven R. Martinez

$T_{cc}^{+}$ is an isoscalar 4-quark state with mass lying barely below the $D^{*+} D^{0}$ threshold, and several times further below the $D^{* 0} D^{+}$ 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…
