Heavy-light hadrons and their excitations

Understand

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).
