Abstract
Building on the recent discovery of the first candidate black hole operator in $\mathcal{N}=4$ super-Yang-Mills, we explore the near-supersymmetric aspects of the theory that capture lightly excited, highly stringy black holes. We extend the superspace formalism describing the classically supersymmetric (1/16-BPS) sector of $\mathcal{N}=4$ super-Yang-Mills and compute a large number of one-loop anomalous dimensions. Despite being in the highly stringy regime, we find hints of a gap in the spectrum, similar to that found by a gravitational path integral. We also determine the actual expression of the first candidate black hole operator at weak gauge coupling, going beyond the cohomological construction.
List of changes
1. We added footnote 4 specifying the regime of our discussion.
2. We added footnote 5 showing that the strict large N limit is well-defined in the space of BPS words.
2. We thank the referee for pointing it out. We rephrased our statement in Sec. 5.1.
