  "abstract": "We prove that the analytic Besov space $B_{p,p}^{1/p}(\\C_+^n)$ embeds continuously into Chang--Fefferman product BMO for every finite $n$ and $1\\le p<\\infty$. Consequently, every small Hankel operator in a finite Schatten class has a product BMO symbol. The proof uses smooth product wavelets and an estimate for dyadic rectangles. We also give a condition on Fejér means that yields a BMO symbol for a bounded Hankel operator on the polydisc.",
