Polish term or phrase: cechowanie
Kontekst: W fizyce pojęcie „cechowanie” odnosi się do sytuacji, w której teoretyczny (matematyczny) opis danego układu uwzględnia pewne wielkości lub parametry, które w praktyce nie mają rzeczywistego, fizycznego znaczenia, tzn. nie można ich zmierzyć.
Używanie takich parametrów bywa jednak przydatne, ponieważ może uprościć opis teoretyczny lub ujawnić pewne własności danego układu.

gauge fixing/choosing a gauge
Explanation:
In the physics of gauge theories, gauge fixing (also called choosing a gauge) denotes a mathematical procedure for coping with redundant degrees of freedom in field variables. By definition, a gauge theory represents each physically distinct configuration of the system as an equivalence class of detailed local field configurations. Any two detailed configurations in the same equivalence class are related by a gauge transformation, equivalent to a shear along unphysical axes in configuration space. Most of the quantitative physical predictions of a gauge theory can only be obtained under a coherent prescription for suppressing or ignoring these unphysical degrees of freedom.




A particular choice of the scalar and vector potentials is a gauge (more precisely, gauge potential) and a scalar function ψ used to change the gauge is called a gauge function. The existence of arbitrary numbers of gauge functions ψ(r, t) corresponds to the U(1) gauge freedom of this theory. Gauge fixing can be done in many ways, some of which we exhibit below.

gauging/imposing gauge


Explanation:
Usually, cechowanie comes together with pole (gauge field), etc. Standing alone, it is a gerund signifying the act of imposing a gauge, or gauging.

ccccccc
The color group SU(3) corresponds to the local symmetry whose gauging gives rise to QCD.
https://en.wikipedia.org/wiki/Quantum_chromodynamics

QCD is formulated in the electric field representation without imposing gauge fixing conditions on gluon fields.
