Explicit Analysis of Kahler Deformations in 4D N=1 Supersymmetric Quiver Theories

Starting from the N = 2 SYM4 quiver theory living on wrapped NiD5 branes around S 2 i spheres of deformed ADE fibered Calabi-Yau threefolds (CY3) and considering deformations using massive vector multiplets, we explicitly build a new class of N = 1 quiver gauge theories. In these models, the quiver gauge group ∏ i U (Ni) is spontaneously broken down to ∏ i SU (Ni) and Kahler deformations are shown to be given by the real part of the integral (2, 1) form of CY3. We also give the superfield correspondence between the N = 1 quiver gauge models derived here and those constructed in hep-th/0108120 using complex deformations. Others aspects of these two dual N = 1 supersymmetric field theories are discussed.
