Black Hole Greybody Factors and Absorption of Scalars by Effective Strings

  title={Black Hole Greybody Factors and Absorption of Scalars by Effective Strings},
  author={Igor R. Klebanov and Samir D. Mathur},
We compute the greybody factors for classical black holes in a domain where two kinds of charges and their anticharges are excited by the extra energy over extremality. We compare the result to the greybody factors expected from an effective string model which was earlier shown to give the correct entropy. In the regime where the left and right moving temperatures are much smaller than the square root of the effective string tension, we find a non-trivial greybody factor which agrees with the… CONTINUE READING
