Fuzzball geometries and higher derivative corrections for extremal holes

Abstract

2-charge D1-D5 microstates are described by geometries which end in ‘caps’ near r = 0; these caps reflect infalling quanta back in finite time. We estimate the travel time for 3-charge geometries in 4-D, and find agreement with the dual CFT. This agreement supports a picture of ‘caps’ for 3-charge geometries. We argue that higher derivative corrections to such geometries arise from string winding modes. We then observe that the ‘capped’ geometries have no noncontractible circles, so these corrections remain bounded everywhere and cannot create a horizon or singularity. giusto@.mps.ohio-state.edu mathur@mps.ohio-state.edu
