             abstract = "We report the discovery of a planetary system from observation of 
                         the high-magnification microlensing event OGLE-2012-BLG-0026. The 
                         lensing light curve exhibits a complex central perturbation with 
                         multiple features. We find that the perturbation was produced by 
                         two planets located near the Einstein ring of the planet host 
                         star. We identify four possible solutions resulting from the 
                         well-known close/wide degeneracy. By measuring both the lens 
                         parallax and the Einstein radius, we estimate the physical 
                         parameters of the planetary system. According to the best-fit 
                         model, the two planet masses are ~0.11MJ and 0.68MJ and they are 
                         orbiting a G-type main-sequence star with a mass ~0.82M. The 
                         projected separations of the individual planets are beyond the 
                         snow line in all four solutions, being ~3.8AU and 4.6AU in the 
                         best-fit solution. The deprojected separations are both 
                         individually larger and possibly reversed in order. This is the 
                         second multi-planet system with both planets beyond the snow line 
                         discovered by microlensing. This is the only such system (other 
                         than the solar system) with measured planet masses without sin i 
                         degeneracy. The planetary system is located at a distance 4.1 kpc 
                         from the Earth toward the Galactic center. It is very likely that 
                         extra light from stars other than the lensed star comes from the 
                         lens itself. If this is correct, it will be possible to obtain 
                         detailed information about the planet host star from follow-up 
                         observation.",
