nLab half-twisted model

Idea

In string theory the term half-twisted model refers to a topological twist of the 2d (2,0)-superconformal QFT (see there for more) which is “in-between” the A-model and the B-model.

The half-twisted model was introduced in

• Edward Witten, Mirror Manifolds And Topological Field Theory, AMS IP studies in Advanced mathematics 9 (1998): 121-160. (arXiv:hep-th/9112056)

as a variant of the A-model/B-model,
