Abstract
Superconducting instability is studied for a one dimensional repulsive system of spinful fermions with double degenerate band. There is no evidence of insulating spin liquid or the D-Mott phase, for any generic fillings. A conventional spin gap phase without any gap in the charge sector (metallic spin gap) is predicted, which is the starting point to investigate the gapless superconducting instability.
