Abstract

The observation of two charged bottomonium-like structures Z b (10610) and Z b (10650) has stimulated extensive studies of the properties of Z b (10610) and Z b (10650). In this talk, we briefly introduce the research status of Z b (10610) and Z b (10650) combined with our theoretical progress.
