Spectroscopy and Decay Constants from Nonperturbative HQET at Order 1/m

We carry out a thorough analysis with the GEVP method to obtain ground-state and first-excited-state masses and decay constants of bottom-strange (pseudo-scalar and vector) mesons. This computation is done for quenched, nonperturbatively renormalized HQET, including order $1\mathrm{/}{m}_b$ terms. The continuum limit is obtained using three lattice spacings and two static actions.
