T-duality Transformation of Gauged Linear Sigma Model with F-term

Understand

We develop the duality transformation rules in two-dimensional theories in the superfield formalism.

• Even if the chiral superfield which we dualize involves an F-term, we can dualize it by virtue of the property of chiral superfields.
• We apply the duality transformation rule of the neutral chiral superfield to the ${\cal N}=(4,4)$ gauged linear sigma model for five-branes.
• We also investigate the duality transformation rule of the charged chiral superfield in the ${\cal N} = (4,4)$ gauged linear sigma model for the $A_1$-type ALE space.
