Black string's tunnelling radiation

We use the Parikh-Wilczek method to study the tunnelling radiation from the event of the black string, which is asymptotically anti-de Sitter and possesses cylindrical symmetry. We show that higher corrections to the semi-classical rate which are caused by energy conservation and angular momentum conservation exist and the emission rate has completely the same functional form as that for spherically symmetric or axisymmetric black holes.
