Abstract
In order to consistently explain controversial experimental results on superconducting states observed by different probes in typical iron-based superconductors, we construct a realistic multiband -wave pairing model by combining the quasiclassical formalism with the first-principles calculation. The model successfully resolves the controversies in contrast to the fact that simplified models such as two-band -wave one fail to do. A key in the model is the existence of relatively small gaps which leads to material-dependent peculiarities.
