This paper explores the neutral particle motion and collisional Penrose process in ergoregion of the braneworld Kerr black hole. We analyze the properties of event horizon, ergosphere and static limit. The particle collision in ergoregion via the Penrose process is investigated. Furthermore, we study the negative energy states and show that the sign of particle energy can be uniquely determined by the sign of angular momentum. In addition, we study the Wald inequality to determine the limits of energy extraction via the Penrose process and also find lower bound of the irreducible mass. The expression for the efficiency of energy extraction from the brane Kerr black hole is found. Finally, we compare our results with that obtained from the Kerr black hole. It is concluded that efficiency increases with the increase of rotation as well as brane parameter b of the black hole.

  1. Observational constraints on the Kerr and its several single-parameter modified spacetimes using quasi-periodic oscillation data

    gr-qc 2025-05 reject novelty 4.0 of 10

    Using quasi-periodic oscillation data under the relativistic precession model, the paper reports 68% constraints on nine modified Kerr spacetimes, with only Kerr-Newman keeping a Kerr-compatible parameter range.
