Abstract
In this work we study the predominantly orbital and radial excitations of hadrons containing a single heavy quark. We present meson and baryon mass splittings and ratios of meson decay constants ( e. g., f(Bs)/f(B) and f(B's)/f(Bs)) resulting from quenched and dynamical two-flavor configurations. Light quarks are simulated using the chirally improved lattice Dirac operator at valence masses as light as M-pi approximate to 350 MeV. The heavy quark is approximated by a static propagator, appropriate for the b quark on our lattices (1/a similar to 1-2 GeV). We also include some preliminary calculations of the O(1/m(Q)) kinetic corrections to the states, showing, in the process, a viable way of applying the variational method to three-point functions involving excited states. We compare our results with recent experimental findings.
