Theory Seminar (High Energy/Cosmology)
Gravity Duals of Dynamical Supersymmetry Breaking
Date: Friday, April 19th
Time: 2:15 pm
Place: 5280 Chamberlin Hall
Speaker: William Cottrell, University of Wisconsin-Madison
Abstract: The AdS/CFT correspondance allows one to study supersymmetry breaking in field theory from the perspective of a gravitational dual. In one scenario, supersymmetry breaking is implemented on the gravity side by inserting antibranes into an otherwise supersymmetric geometry. However, it has been argued that the full backreaction of such a perturbation generates unacceptable singularities and potentially eliminates this class of models. We study these issues in the context of an A_{8} geometry, dual to the ABJM theory of M2 branes. We find that upon inserting anti M2 branes, the perturbative sugra analysis does indeed yield singularities, though we argue that these are smoothed out in the full quantum corrected geometry.
