Gauge-fixing condition on prepotential of chiral multiplet for nongeometric backgrounds
Abstract
We study a supergauge transformation of a complex superfield which generates a chiral superfield in two-dimensional N=(2,2) theory. This complex superfield is referred to as the prepotential of the chiral superfield. Since there exist redundant component fields in the prepotential, we remove some of them by a gauge-fixing condition. This situation is parallel to that of a vector superfield. In order to obtain a suitable configuration of the gauged linear sigma model for the exotic five-brane which gives rise to a nongeometric background, we impose a relatively relaxed gauge-fixing condition. It turns out that the gauge-fixed prepotential is different from a semichiral superfield whose scalar field represents a coordinate of a generalized Kähler geometry.
