The Enhançon and N = 2 Gauge Theory / Gravity RG Flows

  title={The Enhançon and N = 2 Gauge Theory / Gravity RG Flows},
  author={Nick Evans and Clifford V. Johnson and Michela Petrini},
We study the family of ten dimensional type IIB supergravity solutions corresponding to renormalisation group flows from N = 4 to N = 2 supersymmetric SU(N) Yang–Mills theory. Part of the solution set corresponds to a submanifold of the Coulomb branch of the gauge theory, and we use a D3–brane probe to uncover details of this physics. At generic places where supergravity is singular, the smooth physics of the probe yields the correct one–loop form of the effective low energy gauge coupling. The… CONTINUE READING
