Energy extraction and particle acceleration around a rotating black hole in Hořava-Lifshitz gravity
Annotatsiya
The Penrose process on rotational energy extraction of the black hole in the original nonprojectable Ho\ifmmode \check{r}\else \v{r}\fi{}ava-Lifshitz gravity is studied. The strong dependence of the extracted energy from the special range of parameters of the Ho\ifmmode \check{r}\else \v{r}\fi{}ava-Lifshitz gravity, such as parameter ${\ensuremath{\Lambda}}_{W}$ and specific angular momentum $a$, has been found. Particle acceleration near the rotating black hole in Ho\ifmmode \check{r}\else \v{r}\fi{}ava-Lifshitz gravity has been studied. It is shown that the fundamental parameter of the Ho\ifmmode \check{r}\else \v{r}\fi{}ava-Lifshitz gravity can impose a limitation on the energy of the accelerating particles preventing them from the infinite value.
