Most models of the iron-based superconductors find a sign-changing (s\\pm) order parameter [1-6], with the physical implication that pairing is driven by spin fluctuations. Recent work, however, has indicated that LiFeAs has a simple isotropic order parameter [7-9] and spin fluctuations are not necessary [7,10], contrary to the models [1-6]. The strength of the spin fluctuations has been controversial [11,12], meaning that the mechanism of superconductivity cann","authors_text":"A. A. Kordyuk, B. B\\\"uchner, D. V. Evtushinsky, I. V.
