Heavy-light hadrons and their excitations

Abstract

We study the excitations of hadrons containing a single heavy quark. We present meson and baryon mass splittings and ratios of meson decay constants resulting from quenched and dynamical two-flavor configurations. Light quarks are simulated using the Chirally Improved (CI) lattice Dirac operator. The heavy quark is approximated by a static propagator, appropriate for the $b$ quark on our lattices ($1/a\sim 1-2$ GeV). We also include some preliminary calculations of the heavy-quark kinetic corrections to the states.
