Idea

In supersymmetric field theory, Wess-Zumin gauge refers to a choice of gauge fixing of superfields which constrains their dependence on the odd coordinate functions (their super-components, e.g. Buchbinder & Kuzenko 1995, 3.4.3, Tong, §4.1) hence constrains auxiliary fields, but – in contrast to ordinary gauge choices like Lorenz gauge – does not constrain the physical gauge fields.

The authors Atick & Dhar 1987 p. 137 and Tsimpis 2004 suggests to think of Wess-Zumino gauge in supergravity and non-linear sigma-models as a choice of fermionic super-Riemann normal coordinates.
