WebFeb 12, 2024 · In the literature on QFT there are a lot of different equations that are all called "Schwinger-Dyson equation" so I wanted to know how are they related and if … WebApr 10, 2015 · We compute the pion quark Generalized Parton Distribution H {sup q} and Double Distributions F {sup q} and G {sup q} in a coupled Bethe-Salpeter and Dyson-Schwinger approach. We use simple algebraic expressions inspired by the numerical resolution of Dyson-Schwinger and Bethe-Salpeter equations.
WebStarting from the superstring amplitude describing interactions among D-branes with a constant world-volume field strength, we present a detailed analysis of how the open string degeneration limits reproduce the corresponding field theory Feynman diagrams. In perturbative quantum field theory the Schwinger-Dyson equation (Dyson 49, Schwinger 51) equates, on-shell, the time-ordered product of the functional derivative of the action functional SS for a free field theory and another observable AA with the time ordering of the corresponding functional … See more For details and proof see at BV-operator this prop., following Rejzner 16, remark 7.7, following Henneaux-Teitelboim 92, section 15.5.3 See more The equation is originally due to 1.

WebThe Schwinger-Dyson identities are a statement about the regularity behavior of the Witten index in the fugacities . Namely, the vev has many apparent singularities in , but the quantum affine symmetry of the theory eliminates all but a finite number of them, thanks to the dotted terms. WebIt was shown using the Schwinger-Dyson equations and the Slavnov-Taylor identities of Yang-Mills theory that no inconsistency arises if the gluon propagator behaves like (1/p/sup 2/)/sup 2/ for small p/sup 2/. To see whether the theory actually contains such singular long range behavior, a nonperturbative closed set of equations was formulated by neglecting …
Webon Dyson{Schwinger equations, which was already suggested in the work of Bergbauger{Kreimer [2]. In x4 we show that Dyson{Schwinger equations can be formulated in the operad setting, using a family of grafting operations, which is not required to satisfy a cocycle condition. We consider Dyson{Schwinger equations on an operad of ow charts.
