A giant graviton genealogy

Abstract

In this article we extend the construction of giant gravitons from holomorphic surfaces [1] to the ABJM correspondence. We construct a new class of 1/6 {BPS} M5-branes wrapping 5-manifolds in S7 /Zk. and supported by a large angular momentum in the orbifold space. These orbifold giant gravitons undergo a supersymmetry enhancement to 1/3-BPS and 1/2-BPS configurations in special cases. The compactification of M-theory on AdS 4× S7/Zk. to type IIA superstring theory on AdS4 × CP3 then gives rise to another new class of 1/6-BPS D4 and NS5-branes wrapping 4 and 5-manifolds in CP3. The D4-branes carry a combination of D0-brane charge and angular momentum in the complex projective space, while the NS5-branes are supported only by D0-brane charge. Finally, we present a detailed analysis of a one-parameter family of 1/2-BPS M5-brane orbifold giant gravitons, and their D4 and NS5-brane CP 3 descendants. © 2013 SISSA, Trieste, Italy.
