摘要: Ultra high energy cosmic rays (UHECRs) probably originate in extreme conditions which extra dimension effects might be important. In this paper we calculate the correction black hole accretion mechanisms due to static and rotating cases. A parametrization of external Kerr horizons both cases is presented analysed. We use previous calculations upper limits on UHECR flux set production efficiency nine sources. The limit luminosity calculation based GeV-TeV gamma-ray measurements. total mechanism compared UHECRs. dependence mass also discussed
