We introduce and study a family of Banach spaces \(IMO^{s,\sigma }_p\) of functions on the open unit ball \({\mathbb {B}}_n\) in \({\mathbb {C}}^n\), defined by an integrability condition of the mean oscillation in the Bergman metric. Our main results include a decomposition theorem for \(IMO^{s,\sigma }_p\), a characterization of holomorphic functions in \(IMO^{s,\sigma }_p\), and an application of \(IMO^{s,\sigma }_p\) to the boundedness and compactness of Hankel operators between weighted Bergman spaces.
