			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 <math>\theta^1,\theta^2,\bar\theta^1,\bar\theta^2</math>, transforming as a two-component [[spinor]] and its conjugate.

			Every superfield—i.e. a field that depends on all coordinates of the superspace—may be expanded with respect to the new fermionic coordinates. There exists a special kind of superfields, the so-called [[chiral superfield]]s, that only depend on the variables <math>\theta</math> but not their conjugates. The last term in the corresponding expansion, namely <math>F \theta^1\theta^2</math>, is called the '''F-term'''. Applying an infinitesimal supersymmetry transformation to a chiral superfield results in yet another chiral superfield whose F-term, in particular, changes by a total derivative. This is significant because then <math>\int{d^4x\, F(x)}</math> is invariant under SUSY transformations as long as boundary terms vanish. Thus F-terms may be used in constructing supersymmetric actions.

			Manifestly-supersymmetric [[Lagrangian]]s may also be written as [[integral]]s over the whole superspace. Some special terms, such as the [[superpotential]], may be written as integrals over <math>\theta</math>s only. They are also referred to as F-terms, much like the terms in the ordinary potential that arise from these terms of the supersymmetric Lagrangian.
