Bubbling 1/2 BPS solutions of minimal six-dimensional supergravity

Abstract We continue our previous analysis [J.T. Liu, D. Vaman, W.Y. Wen, hep-th/0412043] of 1/2 BPS solutions to minimal 6d supergravity of bubbling form. We show that, by turning on an axion field in the T 2 torus reduction, the constraint F ∧ F , present in the case of an S 1 × S 1 reduction, is relaxed. We prove that the four-dimensional reduction to a bosonic field theory, whose content is the metric, a gauge field, two scalars and a pseudo-scalar (the axion), is consistent. Moreover, these reductions when lifted to the six-dimensional minimal supergravity represent the sought-after family of 1/2 BPS bubbling solutions.
