In theoretical physics, one often analyzes theories with supersymmetry in which F-terms play an important role. In four dimensions, the minimal N=1 supersymmetry may be written using a superspace. This superspace involves four extra fermionic coordinates θ θ 1 , θ θ 2 , θ θ ¯ ¯ 1 , θ θ ¯ ¯ 2 , transforming as a two-component spinor and its conjugate.
