Fr.: jauge de Coulomb
(n.) gaz; (v.) gaz kardan
1) (n.) A standard of measure or measurement, size, or quantity.
From Fr. jauge "gauging rod," perhaps from Frankish galga "rod, pole for measuring;" cf. O.N. gelgja "pole, perch;" O.H.G. galgo; Lith. zalga "pole, perch;" Arm. dzalk "pole;" E. gallows; see below.
Gaz "a yard for measuring cloth; a length of 24 finger-breadths, or six hands; the tamarisk-tree," from Mid.Pers. gaz "tamarisk," may be of the same origin as gauge. In verbal form with kardan "to do, to make" (Mid.Pers. kardan; O.Pers./Av. kar- "to do, make, build;" Av. kərənaoiti "he makes;" cf. Skt. kr- "to do, to make," krnoti "he makes, he does," karoti "he makes, he does," karma "act, deed;" PIE base kwer- "to do, to make").
Fr.: boson de jauge
A class of elementary particles that includes the gluon, photon, W+, W-, and Z0 particles, each having an integral spin.
goruh-e gaz (#)
Fr.: groupe de jauge
The mathematical group associated with a particular set of gauge transformations.
Fr.: invariance de jauge
The invariance of any field theory under gauge transformation.
Fr.: symétrie de jauge
A principle underlying the quantum-mechanical description of the three non-gravitational forces. It allows a system to behave in the same way even though it has undergone various transformations. The earliest physical theory which had a gauge symmetry was Maxwell's electrodynamics.
negare-ye gaz (#)
Fr.: théorie de jauge
A field theory in which it is possible to perform a transformation without altering any measurable physical quantity.
tarâdis-e gaz (#)
Fr.: transformation de jauge
A change of the fields of a gauge theory that does not change the value of any measurable quantity.
Fr.: jauge transverse
Same as the → Coulomb gauge.
