Dualising the baryonic branch: Dynamic SU(2)SU(2) and confining backgrounds in IIA

In this paper we construct and examine new supersymmetric solutions of massive IIA supergravity that are obtained using non-Abelian T-duality applied to the baryonic branch of the Klebanov–Strassler background. The geometries display SU(2)SU(2) structure which we show flows from static in the UV to dynamic in the IR. Confinement and symmetry breaking are given a geometrical interpretation by this change of structure. Various field theory observables are studied, suggesting possible ways to break conformality and flow in N=1TNN=1TN and related field theories.
