Abstract

We present a new supersymmetric, asymptotically flat, black hole solution to five-dimensional U(1)3 supergravity which is regular on and outside an event horizon of lens space topology L(2,1). The solution has seven independent parameters and uplifts to a family of 1/8-supersymmetric D1-D5-P black brane solutions to type IIB supergravity. The decoupling limit is asymptotically AdS3×S3×T4, with a near-horizon geometry that is a twisted product of the near-horizon geometry of the extremal Bañados-Teitelboim-Zanelli black hole and L(2,1)×T4, although it is not (locally) a product space in the bulk. We show that the decoupling limit of a special case of the black lens is related to that of a black ring by spectral flow, thereby supplying an account of its entropy. Analogous solutions of U(1)N supergravity are also presented.
