Spectroscopy of heavy mesons expanded in 1/m(Q)

Starting from the semirelativistic Hamiltonian for a pq system with Coulomb and linear confining scalar potentials, and operating just once with the naive Foldy-Wouthuysen-Tani transformation on the heavy quark, we have calculated the heavy meson mass spectra of D and B together with higher spin states. Based on the formulation recently proposed, their masses and wave functions an expanded up to second order in 1/m(Q) with a heavy quark mass mn and the lowest-order equation is examined carefully to obtain a complete set of eigenfunctions for the Schrodinger equation. Heavy quark effective theory parameters <(Lambda)over bar>, lambda(1), and lambda(2) are also determined at first and second order in 1/m(Q).
