	Gauge theory - Wikipedia, the free encyclopedia
		Gauge theories became even more attractive when it was realized that non-abelian gauge theories reproduced a feature called asymptotic freedom, that was believed to be an important characteristic of strong interactions—thereby motivating the search for a gauge theory of the strong force.
		Gauge theories are usually discussed in the language of differential geometry.
		Note that although gauge theory is dominated by the study of connections (primarily because it's mainly studied by high-energy physicists), the idea of a connection is not essential or central to gauge theory in general.

	Gauge boson - Wikipedia, the free encyclopedia
		Each corresponds to one of the three Standard Model interactions: photons are gauge bosons of the electromagnetic interaction, W and Z bosons carry the weak interaction, and the gluons carry the strong interaction.
		In a quantized gauge theory, gauge bosons are quanta of the gauge fields.
		The role of gauge invariance in general relativity is played by a similar symmetry: diffeomorphism invariance.

	Classical Unified Field Theory
		Gauge symmetry is broken for massive particles by the even, symmetric-matrix term, which is interpreted as being due to gravity.
		The justification for investigating the unified field equation hypothesis is due to the presence of the Maxwell equations.
		From the perspective of this proposal, the freedom to choose a scalar gauge field for the Maxwell equations is due to the omission of the gravitational force field.

	Quantum Field Theory
		The field φ and its conjugate field π are the direct analogues of the canonical coordinate q and the generalized (canonical or conjugate) momentum p in classical mechanics of point particles.
		On this background, Teller has argued in Teller 1995 that the field interpretation of QFT is inappropriate since the alleged fields in QFT are not to be interpreted as physical fields with definite values of some sort which are assigned to space-time points, like in the case of the classical electromagnetic field.
		First, quantum fields which one expects to be somehow physically concrete like classical fields are on the side of observables although, as far as the development of theories is concerned, they are the successors of states (in their position representation, namely wave functions), e.g., in the Klein-Gordon equation of relativistic QM as described above.

	American AntiGravity - Dr. Ning Wu's Gauge-Theory of Gravity
		But in quantum gauge theory of gravity, gravitational force is considered to be a kind of physical interactions, and the concept of curved space-time is only a convenient and equivalent description of the classical effects of gravitational interactions.
		The basic of gauge theory of gravity is the physics picture, and quantum gauge theory of gravity is established in the physics picture of gravity.
		As we have stated above, the transcendental principle of gauge theory of gravity is gauge principle, and and transcendental principles of general relativity is equivalence principle and the principle of general covariance.

	Shooting Times: Benelli's 20-Gauge M1 Field Flies High
		Newly chambered in 20 gauge, Benelli's M1 Field shotguns are direct descendants of the combat-proven M1 Super 90.
		The M1 Field's receiver is made from machined, high-strength anodized aluminum, although the bolt lock-up remains steel-to-steel by virtue of the barrel extension reaching the rotary bolt head.
		The M1 Field 20 gauge is available with either a 24- or 26-inch barrel, complete with ventilated rib and sights that include a red-bar front sight.

		By default, this field displays progress in absolute values (that is, the actual values ranging from the min to the max of this field's range).
		This field's manager invokes this method during the repainting process to instruct this field to repaint itself.
		If an end of this field's allowable range is reached, this method clamps the progress value to the maximum or minimum end of the range (as appropriate) and returns zero.

	Traditions Field II O/U 28 Gauge
		The test model I've been shooting is a member of the Field Hunter line: a Traditions Field II O/U 28 gauge.
		With the Field II O/U series, it's important to note that the 28-gauge and.410 models have a few differences in comparison to the 12- and 20-gauge versions.
		The $759 suggested retail price accompanying the Field II 28 gauge O/U is reasonable, as the shotgun possesses many of the qualities of an O/U that costs a lot more.

		On top of this, all of the calculations are done with component fields; superfields are used only for organization.
		B&L don't bother with conformal field theory at all and use basically the "old covariant quantization".
		I really enjoyed the observations of professor Bailin about gauge theory, which is quite useful in the field of submoleculer physics and wave theory.

	Induced gauge field concept
		Classical color fields are identified as the projections of the color Killing vectors to the spacetime surface in close parallel to the corresponding construction in Kaluza-Klein theories.
		Classical color fields are also an unavoidable prediction of TGD (classical electromagnetic fields are accompanied by classical color fields) and even macroscopic 3-surfaces can have nontrivial color quantum numbers resulting from their center of mass motion in CP_2 degrees of freedom.
		In the quantum field theory limit one can identify graviton and gauge boson fields as linear quantum deformations of the H-vielbein and spinor connection and the quantum fields on the spacetime surface are obtained by the induction from this field.

		Thank u for your interest in my question, the story here, physically talking means that the gauge field is the non-abelain gauge field "A_{mu}, and the field strength is the F_{mu nu}.
		the gauge field is not the one of the gravidation
		In the case u do,u'll find that your problem reduces to checking the validity of that equality only in the case of the 2 fundamental (possibly inequivalent) irreps of the gauge group:the fundamental and its contragradient one.
