Abstract
The dynamics of massive particles near the horizons of charged rotating and charged accelerating black holes is studied. This is done, in particular, from the point of view of studying the screening effect of Hawking radiation and shielding of the Penrose process for these two black holes. We do this by identifying the forbidden regions which are the regions where the particles have negative kinetic energy. The screening and shielding processes are studied via quantum tunnelling of particles through these regions. The dependence of these processes on angular momentum and energy of particles, and the role of acceleration and the charge of black holes is explored in detail.
