Holographic MQCD

Understand

We study a brane configuration of D4-branes and NS5-branes in weakly coupled type IIA string theory, which describes in a particular limit d=4 N=1 SU(N+p) supersymmetric QCD with 2N flavors and a quartic superpotential.

• We describe the geometric realization of the supersymmetric vacuum structure of this gauge theory.
• We focus on the confining vacua of the gauge theory, whose holographic description is given by the MQCD brane configuration in the near-horizon geometry of N D4-branes.
• This description, which gives an embedding of MQCD into a field theory decoupled from gravity, is valid for 1 << p << N, in the limit of large five dimensional `t Hooft couplings for the color and flavor groups.
