| contents | We use a slave-boson approach to study the band renormalization and pair susceptibility in the normal state of Iron-based superconductors in presence of strong Coulomb repulsion and Hund's interaction. Our results show orbital selectivity toward localization of $xy$ orbitals and its interplay with superconductivity. We also compare the recently proposed triplet resonating valence bond theory of superconductivity in Iron-based superconductors with the more conventional $s_\pm$ pairing and show that both favor a superconductivity when the $xy$ orbital is delocalized. |
