The decoupling of Ω¯ in string theory
In this note, we study the deformation of the topological string by Ω¯. Namely, adopting the perturbative string amplitudes approach, we identify the Ω¯-deformation in terms of a physical state in the sting spectrum. We calculate the topological amplitudes Fg in heterotic string theory in the presen...
