Recursion equations in gauge field theories

Webthis case, the local trivializations are thought of as choices of gauge, while the transition function is usually called a gauge transformation. For example, a familiar case might be to choose M ∼= R3,1 and G ∼= U(1), whereupon for each x we could write t(x) = eiλ(x) ∈ U(1) with λ(x) a gauge parameter in electrodynamics. Another example ... WebColor-factor symmetry is a property of tree-level gauge-theory amplitudes containing at least one gluon. BCJ relations among color-ordered amplitudes follow directly from this symmetry. Color-factor symmetry is also a feature of biadjoint scalar theory amplitudes as well as of their equations of motion. In this paper, we present a new proof of color-factor …

WebAbstract. Migdal’s recursion equation proposed for the Wilson lattice gauge theory is studied for its weak and strong coupling behavior. The model is then solved numerically for the SU(2) gauge field, and it is shown that there is a continuous crossover from the weak coupling (asymp-totically free) region to the strong coupling (quark confining) domain. WebApr 11, 2024 · This recursion relation is related to the loop equations of minimal string theory, which can be described by an SFT through the Fokker–Planck formalism. Accordingly, I convert the recursion relation into an SFT using a Fokker–Planck Hamiltonian consisting of kinetic terms and three-string vertices.
