Script N = 1/2 quiver gauge theories from open strings with RR fluxes
Abstract
We consider a four dimensional Script N = 1 gauge theory with bifundamental matter and a superpotential, defined on stacks of fractional branes. By turning on a flux for the RR graviphoton field strength and computing open string amplitudes with insertions of RR closed string vertices, we introduce a nonanticommutative deformation and obtain the Script N = 1/2 version of the theory. We also comment on the appearance of a new structure in the effective lagrangian.
