Motion of charged particles around a scalarized black hole in Kaluza-Klein theory

In this article we study the motion of charged particles in the spacetime of a charged rotating scalarized black hole, namely the rotating dyonic black hole in Kaluza-Klein theory found by Rasheed. We derive the equations of motion in the extremal case and present their analytical solutions in terns of elliptic and hyperelliptic functions. Furthermore, we analyze the particle motion with the help of parametric diagrams and effective potentials.
