One-Loop Self-Dual and N=4 Super Yang-Mills
Z. Bern, L. Dixon, D. C. Dunbar +1
We conjecture a simple relationship between the one-loop maximally helicity violating gluon amplitudes of ordinary QCD (all helicities identical) and those of N=4 supersymmetric Ya…
Counting Schwarzschild and Charged Black Holes
E. Halyo, B. Kol, A. Rajaraman +1
We review the arguments that fundamental string states are in one to one correspondence with black hole states. We demonstrate the power of the assumption by showing that it implie…
Classical and Quantum Aspects of BPS Black Holes in N=2, D=4 Heterotic String Compactifications
Soo-Jong Rey
We study classical and quantum aspects of D=4, N=2 BPS black holes for T_2 compactification of D=6, N=1 heterotic string vacua. We extend dynamical relaxation phenomena of moduli f…
Fixed Scalars and Suppression of Hawking Evaporation
Barak Kol, Arvind Rajaraman
For an extreme charged black hole some scalars take on a fixed value at the horizon determined by the charges alone. We call them fixed scalars. We find the absorption cross sectio…
STU Black Holes and String Triality
Klaus Behrndt, Renata Kallosh, Joachim Rahmfeld +2
We find double-extreme black holes associated with the special geometry of the Calabi-Yau moduli space with the prepotential F=STU. The area formula is STU-moduli independent and h…
Freezing of Moduli by N=2 Dyons
Renata Kallosh, Marina Shmakova, Wing Kai Wong
In N=2 ungauged supergravity we have found the most general double-extreme dyonic black holes with arbitrary number n_v of constant vector multiplets and n_h of constant hypermulti…
