Abstract
We present a study of interspecies Feshbach resonances in ultracold Li-Cs Bose-Bose mixtures. We locate ten interspecies resonances in three different spin-state combinations. By comparing to coupled-channel calculations, we assign six of the resonances to -wave channels and the rest to -wave channels. We use the -wave resonances to refine the ground-state potentials of LiCs in the coupled-channel calculations and then obtain an accurate characterization of the scattering and bound-state properties of the mixtures. Our results will be useful for future experiments with ultracold Li-Cs mixtures.
