String junctions and bound states of intersecting branes
- Department of Physics, University of Illinois at Urbana-Champaign, Urbana, Illinois 61801 (United States)
We study four-dimensional black hole configurations which result from wrapping M5-branes on a Calabi-Yau manifold, as well as {ital U}-dual realizations. Our aim is to understand the microscopic degrees of freedom responsible for the existence of bound states of multiple branes. The details depend on the chosen {ital U} frame; in some cases, they are massless string junctions. We also identify a perturbative description in which these states correspond to twisted strings of intersecting D3-branes at an orbifold singularity. In each case, these are the preponderant states of the spacetime infrared conformal field theory and account for the entropy of the black hole. {copyright} {ital 1999} {ital The American Physical Society}
