Energy extraction and particle acceleration around a rotating black hole in Hořava-Lifshitz gravity

The Penrose process on rotational energy extraction of the black hole in the original nonprojectable Ho {r} {r}{}ava-Lifshitz gravity is studied. The strong dependence of the extracted energy from the special range of parameters of the Ho {r} {r}{}ava-Lifshitz gravity, such as parameter ΛW and specific angular momentum a, has been found. Particle acceleration near the rotating black hole in Ho {r} {r}{}ava-Lifshitz gravity has been studied. It is shown that the fundamental parameter of the Ho {r} {r}{}ava-Lifshitz gravity can impose a limitation on the energy of the accelerating particles preventing them from the infinite value.
