TUNNELING OF CHARGED FERMIONS FROM THE GARFINKLE-HORNE DILATON BLACK HOLE

摘要

Motivated by the recent work of Kerner and Mann, we study Hawking tunneling radiation of fermions from the Garfinkle-Horne dilaton black hole on the brane. Because the electromagnetic field would couple with the gravity and matter fields, we introduce the Dirac equation of charged particles. We further discuss the correction spectrum of the radiant spin 1/2 particles by considering energy conservation and charge conservation. Our result shows that the tunneling rate of fermions also agrees with the underlying unitary theory as the unfixed background space-time is taken into account.
