Gauge invariance of wilson line
Did you know?
To properly define Wilson loops in gauge theory requires considering the fiber bundle formulation of gauge theories. Here for each point in the -dimensional spacetime there is a copy of the gauge group forming what's known as a fiber of the fibre bundle. These fiber bundles are called principal bundles. Locally the resulting space looks like although globally it can have some twisted structure … WebFeb 1, 2001 · (13) as a complete set of gauge invariant observables of the dual noncommutative U(1) gauge theory. 4. For small total energy or momentum, k ⪡1/ θ D, separation between the Wilson line endpoints is shorter than the noncommutativity scale, θ D. Hence, the Wilson line reduces effectively to a (Fourier-transform) of the standard …
WebDec 21, 2024 · A Wilson loop or Wilson line is an observable in (both classical and quantum) gauge theory obtained from the holonomy of the gauge connection. Hence if … WebA range of issues pertaining to the use of Wilson lines in integrated and transverse-momentum dependent (TMD) parton distribution functions (PDF) is discussed. The relation between gauge invariance and the renormalization properties of the Wilson-line integrals is given particular attention. Using an anomalous-dimensions based analysis in the light …
Weba(x) is gauge invariant 1. The gauge invariance arises from two features we will try to emulate in the gravitational context. First, the trace over the index acancels the transformations of the Wilson line against the transformation of the operator. The second feature is that we are only dividing out by the gauge transformations such that g(y ... WebAn insertion of Wilson line operator plays the role of off-shell or reggeized gluon in such formulation. Keeping in mind an extremely important role played by Wilson loops in N = …
WebFeb 2, 2024 · In particular, we address issues that appear when one attempts to trivialize the Wilson lines in the correlation functions by gauge fixing. We find it is always impossible to completely remove the gauge fields n · A in Wilson lines that extend to infinity in the n direction by means of gauge transformations. We show how the obstruction appears ...
Webi.e., Wilson lines [30]. A Wilson line physically describes the insertion of an (infinitely heavy) charged test particle that moves on a worldline γ: W RðγÞ¼tr R Pexp i Z γ Aμdxμ; ð1Þ where R is the representation of the gauge group. For a timelike γ, we can think of the Wilson line as a localized charged impurity—it changes the ... molly wood virginianWebThis method guarantees the gauge invariance of observables order by order in the strong coupling. The quark and gluon PDFs for the dressed quarks are obtained in the QTM at leading order.
