Title Collision of particles and energy extraction in hyperscaling violation background
Type JournalPaper
Keywords Collision of particles,energy extraction,hyperscaling violation background
Abstract In this paper, we investigate particle collision near the charged black hole with hyperscaling violating factor under different conditions on mass, charge and θ parameters. In that case, we calculate the center of mass (CM) energy of two colliding particles on the black hole horizon. We find that unlike the other stationary black holes that have been studied so far, the center of mass energy on the horizon can be infinite in certain conditions. By computing the effective potential, we found that particles can collide with very high CM energy on the horizon at two states. The first is an uncharged black hole with small mass and small θ. The second is a massive black hole with the small value of charge and θ. In addition, we investigate the geodesic motion of particles and plot some possible orbits around this black hole. Then, we obtain the ergosphere extent of the hyperscaling violation charged black hole and found that increasing value of θ, the ergoregion limit reduces and we can not extract energy with large value of θ. We also found that energy extraction from the black hole only depends on the absorbed charge by the black hole
