2d (0,2) Quiver Gauge Theories and D-Branes

Understand

We initiate a systematic study of 2d (0,2) quiver gauge theories on the worldvolume of D1-branes probing singular toric Calabi-Yau 4-folds.

• We present an algorithm for efficiently calculating the classical mesonic moduli spaces of these theories, which correspond to the probed geometries.
• We also introduce a systematic procedure for constructing the gauge theories for arbitrary toric singularities by means of partial resolution, which translates to higgsing in the field theory.
• Finally, we introduce Brane Brick Models, a novel class of brane configurations that consist of D4-branes suspended from an NS5-brane wrapping a holomorphic surface, tessellating a 3-torus.
