title = "U(1) symmetric α-attractors",
abstract = "We present a class of supergravity α-attractors with an approximate global U(1) symmetry corresponding to the axion direction. We also develop a multi-field generalization of these models and show that the α-attractor models with U(1) symmetries have a dual description in terms of a two-form superfield coupled to a three-form superfield.",
