Dualising the Baryonic Branch: Dynamic SU(2) and confining backgrounds in IIA

Understand

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) structure which we show flows from static in the UV to dynamical 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 $N=1$ $T_N$ and related field theories.
