WebAn important phenomenon discussed especially in the context of quantum field theories is local gauge invariance (e.g. []).In our models this phenomenon can potentially arise as …
WebTo remedy this we argue that one needs to introduce a new Wilson line as part of SCET formalism, that we call T. This Wilson line depends only on the transverse component of the gluon eld. As such it is a new feature to the SCET formalism and it guarantees gauge invariance of the non-perturbative matrix elements in both classes of gauges. WebMay 29, 2024 · (c) and (d) The two traces correspond to Wilson line integrals, without (dotted red line) the U (2) gauge transformation in Eq. and with it (solid blue line); they …
WebNov 21, 2016 · The purpose of this book is to give a systematic pedagogical exposition of the quantitative analysis of Wilson lines and gauge-invariant correlation functions in quantum chromodynamics. Using techniques from the previous volume (Wilson Lines in Quantum Field Theory, 2014), an ab initio methodology is developed and practical tools … WebFeb 8, 2024 · specified by the vector v, and is necessary to ensure gauge invariance of the correlator. The gauge links contain transverse pieces at infinity [15, 16] and their precise form depends on the process [17, 18]. In a covariant gauge, the dependence of the correlator Φ on vis evident from the presence of the Wilson line in the direction ...

The correct statement is that the Wilson loop observables generate via limits and algebraic operations all of the other observables in pure gauge theory. Obviously the finite size Wilson loops are not the only observables.

The gauge invariance (a) is manifest because of the use of the open Wilson line [14] – [16]. We will show that it also satisfies the Bianchi identity (b) and the initial condition (c). 2.1 Bianchiidentity In order to prove the Bianchi identity, it is useful to introduce the following currents of rank 2s, J i1··· 2s(k ... ishares tr mbs etfWebator corresponds to an off-shell gluon (and additional contributions needed by the gauge invariance), while the direction of the Wilson line corresponds to its “polarization” vector.
