Bubbling the Newly Grown Black Ring Hair    [PDF]

New families of BPS black ring solutions with four electric and four dipole
magnetic charges have recently been explicitly constructed and uplifted to
M-theory. These solutions were found to belong to a CFT with central charge
different compared to the one of the STU model. Because of their importance to
AdS/CFT, here we give the microstate description of these geometries in terms
of topological bubbles and supertubes. The fourth charge results in an
additional flux through the topological cycles that resolve the brane
singularities. The analog of these solutions in the IIB frame yield a
generalized regular supertube with three electric charges and one dipole
charge. Direct comparison is also made with the previously-known bubbled
geometries.
