Black Rings with Varying Charge Density
Iosif Bena, Chih-Wei Wang, Nicholas P. Warner
We find the general five-dimensional, supersymmetric black ring solutions in M-theory based upon a circular ring, but with arbitrary, fluctuating charge distributions around the ri…
Loops in Twistor Space
Iosif Bena, Zvi Bern, David A. Kosower +1
We elucidate the one-loop twistor-space structure corresponding to momentum-space MHV diagrams. We also discuss the infrared divergences, and argue that only a limited set of MHV d…
Microscopic Description of Black Rings in AdS/CFT
Iosif Bena, Per Kraus
We discuss some aspects of the recently discovered BPS black ring solutions in terms of the AdS/CFT correspondence. In the type IIB frame in which the black ring carries the charge…
One Ring to Rule Them All ... and in the Darkness Bind Them?
Iosif Bena, Nicholas P. Warner
We construct all eleven-dimensional, three-charge BPS solutions that preserve a fixed, standard set of supersymmetries. Our solutions include all BPS three-charge rotating black ho…
Twistor-Space Recursive Formulation of Gauge-Theory Amplitudes
I. Bena, Z. Bern, D. A. Kosower
Using twistor space intuition, Cachazo, Svrcek and Witten presented novel diagrammatic rules for gauge-theory amplitudes, expressed in terms of maximally helicity-violating (MHV) v…
A harmonic family of dielectric flow solutions with maximal supersymmetry
Iosif Bena, Nicholas P. Warner
We construct a new harmonic family: dielectric flow solutions with maximal supersymmetry in eleven-dimensional supergravity. These solutions are asymptotically AdS_4 x S^7, while i…
Splitting hairs of the three charge black hole
Iosif Bena
We construct the large radius limit of the metric of three charge supertubes and three charge BPS black rings by using the fact that supertubes preserve the same supersymmetries as…
Three Charge Supertubes and Black Hole Hair
Iosif Bena, Per Kraus
We construct finite size, supersymmetric, tubular D-brane configurations with three charges, two angular momenta and several brane dipole moments. In type IIA string theory these a…
Towards the solution to the giant graviton puzzle
Iosif Bena, Douglas Smith
In this note we present several ideas toward the solution to the giant graviton puzzle - the apparent multiplicity of supergravity states dual to field theory chiral primary operat…
