Abstract
The discovery of high-Tc superconductivity in the pnictides, materials with a Fermi surface determined by
several bands, highlights the need to understand how superconductivity arises in multiband systems. In this
effort, using symmetry considerations and mean-field approximations, we discuss how strong hybridization
among orbitals may lead to both intraband and interband pairings, and we present calculations of the spectral
functions to guide the experimental search for this kind of state.
