Abstract
We review the main ingredients for an unconventional pairing state in the ferropnictides, with particular emphasis on interband pairing due to magnetic fluctuations. Summarizing the key experimental prerequisites for such pairing, the electronic structure and nature of magnetic excitations, we discuss the properties of the s+/- state that emerges as a likely candidate pairing state for these materials and survey experimental evidence in favor of and against this novel state of matter.
