# Motion and collision of particles near DST black holes

@article{Gonzlez2019MotionAC, title={Motion and collision of particles near DST black holes}, author={Pablo A. Gonz{\'a}lez and Marco Olivares and Ali {\"O}vg{\"u}n and Joel Saavedra and Yerko V{\'a}squez}, journal={The European Physical Journal C}, year={2019}, volume={79}, pages={1-14} }

We consider the Deser–Sarioglu–Tekin (DST) black hole as a background, and we study the motion of massive particles in the case that we have a collision of two spinning particles in the vicinity of its horizon. New kinds of orbits are allowed for small deviations of General Relativity, but the behavior of the collision is similar to the one observed for General Relativity. Some observables like the bending of light and the perihelion precession are analyzed.
