D-MESONS IN A RELATIVISTIC QUARK-MODEL

A relativistic quark model which was previously developed and applied to heavy-quark systems is applied to the light-heavy-quark D mesons. Kernels are generated for the bound-state amplitudes of unequal quark-mass systems in this model, which is essentially the Coulomb-gauge QCD Hamiltonian, augmented by a scalar linearly confining term. The model generates all the correct perturbative physics up to order alpha(s)(4). Results are compared to experimental data.
