Fivebranes from gauge theory
We study theories with sixteen supercharges and a discrete energy spectrum. One class of theories has symmetry group SU(2|4). They arise as truncations of N = 4 super Yang Mills. They include the plane wave matrix model, 2+1 super Yang Mills on R × S2 and N = 4 super Yang Mills on R × S/Zk. We explain how to obtain their gravity duals in a unified way. We explore the regions of the geometry tha...
متن کاملM-momentum Transfer between Gravitons, Membranes, and Fivebranes as Perturbative Gauge Theory Processes
Polchinski and Pouliot have shown that M-momentum transfer between membranes in supergravity can be understood as a non-perturbative instanton effect in gauge theory. Here we consider a dual process: electric flux transmission between D-branes. We show that this process can be described in perturbation theory as virtual string pair creation, and is closely related to Schwinger’s treatment of th...
متن کاملFivebranes, Membranes and Non-perturbative String Theory
Non-perturbative instanton corrections to the moduli space geometry of type IIA string theory compactified on a Calabi-Yau space are derived and found to contain order e−1/gs contributions, where gs is the string coupling. The computation reduces to a weighted sum of supersymmetric extremal maps of strings, membranes and fivebranes into the Calabi-Yau space, all three of which enter on equal fo...
متن کاملNS Fivebranes in Type 0 String Theory ∗
The massless degrees of freedom of type 0 NS5-branes are derived. A non-chiral, purely bosonic spectrum is found in both type 0A and 0B. This non-chirality is confirmed by a one-loop computation in the bulk. An interpretation of the spectra in terms of “type 0 little strings” is proposed. The type 0B NS5-brane is conjectured to be dual to a bound state of certain D5-branes, which is argued to h...
متن کاملGravitational Anomaly Cancellation for M -Theory Fivebranes
We study gravitational anomalies for fivebranes in M theory. We show that an apparent anomaly in diffeomorphisms acting on the normal bundle is cancelled by a careful treatment of the M theory Chern-Simons coupling in the presence of fivebranes. One interesting aspect of our treatment is the way in which a magnetic object (the fivebrane) is smoothed out through coupling to gravity and the resul...
