Black hole entropy in MTheory
Abstract
Extremal black holes in Mtheory compactification on M × S^{1} are microscopically represented by fivebranes wrapping P × S^{1}, where M is a CalabiYau threefold and P is a fourcycle in M. Additional spacetime charges arise from momentum around the S^{1} and expectation values for the selfdual threeform field strength in the fivebrane. The microscopic entropy of the fivebrane as a function of all the charges is determined from a twodimensional (0,4) sigma model whose target space includes the fivebrane moduli space. This entropy is compared to the macroscopic formula. Precise agreement is found for both the treelevel and oneloop expressions.
