We study the greybody factors, the reflection and transmission coefficients for a non-minimally coupled massive scalar field in a d-dimensional topological massless black hole background in the zero-frequency limit. We show that there is a range of modes contributing to the absorption cross section, contrary to the current results where the only contribution comes from the mode with lowest angular momentum.
