Abstract:

We study effective gravitational F-terms, obtained by integrating an U(N) adjoint chiral superfield φ coupled to the N = 1 gauge chiral superfleld Wα and supergravity, to arbitrary orders in the gravitational background. The latter includes in addition to the M = 1 Weyl superfield G αβγ, the self-dual graviphoton field strength F αβ of the parent, broken N = 2 theory. We first study the chiral ring relations resulting from the above non-standard gravitational background and find agreement, fo...
