Schwinger-dyson Equation for Non-lagrangian Field Theory
A method is proposed of constructing quantum correlators for a general gauge system whose classical equations of motion do not necessarily follow from the least action principle. The idea of the method is in assigning a certain BRST operator Ω̂ to any classical equations of motion, Lagrangian or not. The generating functional of Green’s functions is defined by the equation Ω̂Z(J) = 0 that is redu...
متن کاملSchwinger-Dyson approach to non-equilibrium classical field theory
In this paper we discuss a Schwinger-Dyson [SD] approach for determining the time evolution of the unequal time correlation functions of a non-equilibrium classical field theory, where the classical system is described by an initial density matrix at time t = 0. We focus on λφ4 field theory in 1+1 space time dimensions where we can perform exact numerical simulations by sampling an ensemble of ...
متن کاملDyson - Schwinger Equation Studies
The dichotomy of the pion as QCD's Goldstone mode and a bound state of massive constituents is easily understood using the Dyson-Schwinger equations. That provides the foundation for an efficacious phenomenology, which correlates the pion's charge radius and electromagnetic form factor with its valence quark distribution function; and simultaneously provides a Poincaré covariant description of ...

متن کاملCombinatorial Dyson-Schwinger equations in noncommutative field theory
We introduce here the Hopf algebra structure describing the noncommutative renormalization of a recently introduced translation-invariant model on Moyal space. We define Hochschild one-cocyles B γ + which allows us to write down the combinatorial DysonSchwinger equations for noncommutative quantum field theory. Oneand two-loops examples are explicitly worked out.
