Can Virtual Cosmic Strings Shift the Hawking Temperature?

Abstract
The amount of the Hawking radiation in Hartle-Hawking vacuum around the Schwarzschild black hole is calculated in the presence of the cloud of virtual-cosmic-string loops near the black hole. Recently, Coleman, Preskill and Wilczek have discussed the black-hole temperature in such situation. We show, in this letter, it is hardly possible to find any deviation in the Hawking radiation even if the virtual cosmic strings exist.
