The discovery of giant planets on wide orbits represents a major challenge for the standard core accretion model. In such model, giant planets are expected to form at small or moderate distances from the central star in order to form massive cores able to trigger the gaseous runaway growth before the dissipation of the disk. In this work, we present a new simple mechanism for the formation of giant planets on wide orbits by core accretion considering planet formation, planet migration and disk evolution.
