We report the discovery and the analysis of the planetary microlensing event , OGLE-2013-BLG-1761 .
There are some degenerate solutions in this event because the planetary anomaly is only sparsely sampled .
But the detailed light curve analysis ruled out all stellar binary models and shows that the lens to be a planetary system .
There is the so-called close/wide degeneracy in the solutions with the planet/host mass ratio of q \sim ( 7.5 \pm 1.5 ) \times 10 ^ { -3 } and q \sim ( 9.3 \pm 2.9 ) \times 10 ^ { -3 } with the projected separation in Einstein radius units of s = 0.95 ( close ) and s = 1.19 ( wide ) , respectively .
The microlens parallax effect is not detected but the finite source effect is detected .
Our Bayesian analysis indicates that the lens system is located at D _ { L } = 6.9 _ { -1.2 } ^ { +1.0 } { kpc } away from us and the host star is an M/K-dwarf with the mass of M _ { L } = 0.33 _ { -0.18 } ^ { +0.32 } M _ { \sun } orbited by a super-Jupiter mass planet with the mass of m _ { P } = 2.8 _ { -1.5 } ^ { +2.5 } M _ { Jup } at the projected separation of a _ { \perp } = 1.8 _ { -0.5 } ^ { +0.5 } { AU } .
The preference of the large lens distance in the Bayesian analysis is due to the relatively large observed source star radius .
The distance and other physical parameters can be constrained by the future high resolution imaging by ground large telescopes or HST .
If the estimated lens distance is correct , this planet provides another sample for testing the claimed deficit of planets in the Galactic bulge .
