Debris disks, which are optically thin, dusty disks around main sequence stars, often found to have structures and/or asymmetries associated with planet-disk interactions. disk morphologies can hence be used as probes for planets in these systems unlikely detected other current exoplanet detection methods. In this study we take a look at the very asymmetrical debris HD 111520, harbours several signs of perturbation such ``fork"-like structure NW, well 4$^{\circ}$ warp from midplane on either side disk. We simulate complicated morphology using code REBOUND, goal constraining possible mass and orbit planet responsible observed structures. find that $\sim$1 M$_{jup}$, eccentric is inclined relative has semi-major axis $\gtrsim$200 au, able reproduce majority features including warp, fork radial extent asymmetry. To create surface brightness asymmetry, second required inside inner edge (50 au), although unable produce 2 1 asymmetry observed, suggesting mechanism may required.
