Chiral flavors and M2-branes at toric CY4 singularities

Understand

We extend the stringy derivation of N=2 AdS4/CFT3 dualities to cases where the M-theory circle degenerates at complex codimension-two submanifolds of a toric conical CY4.

• The type IIA backgrounds include D6-branes, and the dual N=2 quiver gauge theories contain chiral flavors.
• We provide a general recipe to derive the geometric moduli space of flavored versions of Abelian toric quiver gauge theories.
• The CY4 cone is reproduced thanks to a non-trivial quantum F-term relation between diagonal monopole operators and bifundamental fields.
