We present the discovery of two planetary systems consisting of a Saturn-mass planet orbiting an M-dwarf , which were detected in faint microlensing events OGLE-2013-BLG-0132 and OGLE-2013-BLG-1721 .
The planetary anomalies were covered with high cadence by OGLE and MOA photometric surveys .
The light curve modeling indicates that the planet-to-host mass ratios are ( 5.15 \pm 0.28 ) \times 10 ^ { -4 } and ( 13.18 \pm 0.72 ) \times 10 ^ { -4 } , respectively .
Both events were too short and too faint to measure a reliable parallax signal and hence the lens mass .
We therefore used a Bayesian analysis to estimate the masses of both planets : 0.29 ^ { +0.16 } _ { -0.13 } M _ { Jup } ( OGLE-2013-BLG-0132Lb ) and 0.64 ^ { +0.35 } _ { -0.31 } M _ { Jup } ( OGLE-2013-BLG-1721Lb ) .
Thanks to a high relative proper motion , OGLE-2013-BLG-0132 is a promising candidate for the high-resolution imaging follow-up .
Both planets belong to an increasing sample of sub-Jupiter-mass planets orbiting M-dwarfs beyond the snow line .
