Non-extremal instantons and wormholes in string theory
Open accessAbstract
We construct the most general non‐extremal spherically symmetric instanton solution of a gravity‐dilaton‐axion system with SL(2, R) symmetry, for arbitrary euclidean spacetime dimension D≥ 3. A subclass of these solutions describe completely regular wormhole geometries, whose size is determined by an invariant combination of the SL(2, R) charges. Our results can be applied to four‐dimensional effective actions of type II strings compactified on a Calabi‐Yau manifold, and in particular to the universal hypermultiplet coupled to gravity. We show that these models contain regular wormhole solutions, supported by regular dilaton and RR scalar fields of the universal hypermultiplet.

It has by now been established that wormhole solutions do really arise in string-derived models.
“We also briefly comment on dilatonic instantons as they generically arise in string theory, emphasizing that it has by now been established that wormhole solutions do really arise in string-derived models (Tamvakis, 1989;Bergshoeff et al., 2005;Arkani-Hamed et al., 2007b;Hertog et al., 2017).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
