We explicitly evaluate one-loop (annulus) planar and nonplanar open string amplitudes in the presence of the background NS–NS two-form field. In the decoupling limit of Seiberg and Witten, we find that the nonplanar string amplitudes reproduce the UV/IR mixing of noncommutative field theories. In pa...
