Fixed scalar greybody factors in five and four dimensions

  title={Fixed scalar greybody factors in five and four dimensions},
  author={Igor R. Klebanov and Michael Krasnitz},
We perform the classical gravity calculations of the fixed scalar absorption cross-sections by D = 5 black holes with three charges and by D = 4 black holes with four charges. We obtain analytic results for the cases where the energy and the left and right moving temperatures are sufficiently low but have arbitrary ratios. In D = 5 the greybody factor is in perfect agreement with the recent calculation performed in the context of the effective string model for black holes. In D = 4 the formula… CONTINUE READING
