We investigate the nature of superfluid pairing in a strongly interactingFermi gas near orbital Feshbach resonances with spin-population imbalance inthree dimensions, which can be well described by a two-band or two-channelmodel. We show that a Sarma superfluid with gapless single-particle excitationsis favored in the closed channel at large imbalance. It is thermodynamicallystable against the formation of an inhomogeneous Fulde\textendashFerrell\textendash Larkin\textendash Ovchinnikov superfluid and features awell-defined Goldstone-Anderson-Bogoliubov phonon mode and a massive Leggettmode as collective excitations at low momentum. At large momentum, the Leggettmode disappears and the phonon mode becomes damped at zero temperature, due tothe coupling to the particle-hole excitations. We discuss possible experimentalobservation of a strongly interacting Sarma superfluid with ultracoldalkaline-earth-metal Fermi gases.
