SUMMARY:Over-Extremal Brane Shells from String Theory\, Theory Seminar
  (High Energy/Cosmology)\, Vincent Van Hemelryck\, Leuven U.
DESCRIPTION:In this talk\, I will argue that there must exist spherica
 l brane shells in 4d that are overcharged\, if the usual phenomenologi
 cal compactifications of type IIB string theory with warped throats an
 d anti-branes make sense. These shells correspond to classical over-ex
 tremal objects but without the usual naked singularities. The objects 
 are made from D3-particles that puff into spherical 5-branes that stab
 ilise at finite radii in 4d and whose inside corresponds to the supers
 ymmetric AdS vacuum. We find that these objects can be significantly l
 arger than the string scale depending on the details of the warped com
 pactification.
