New infinite class of 6d , N=(1,0) supergravities

Abstract

We present a new infinite class of non-Abelian, 6d supergravities with eight supercharges. These theories not only satisfy all known low-energy consistency conditions, such as being free of anomalies, but also evade the constraints arising from the consistency of string probes, even after assuming completeness of the Bogomol’nyi–Prasad–Sommerfield (BPS) spectrum. This demonstrates that some additional UV input or hitherto unknown IR condition is needed in order to be left with a finite landscape, as is generally anticipated from a theory of quantum gravity.
