New N=1 dualities from orientifold transitions - Part I: Field Theory

Understand

We report on a broad new class of N=1 gauge theory dualities which relate the worldvolume gauge theories of D3 branes probing different orientifolds of the same Calabi-Yau singularity.

• In this paper, we focus on the simplest example of these new dualities, arising from the orbifold singularity C^3/Z_3.
• We present extensive checks of the duality, including anomaly matching, partial moduli space matching, matching of discrete symmetries, and matching of the superconformal indices between the proposed duals.
• We then present a related duality for the dP_1 singularity, as well as dualities for the F_0 and Y^{4,0} singularities, illustrating the breadth of this new class of dualities.
