Semiclassical Trans-Series from the Perturbative Hopf-Algebraic Dyson-Schwinger Equations: phi3 QFT in 6 Dimensions

نویسندگان

چکیده

We analyze the asymptotically free massless scalar $\phi^3$ quantum field theory in 6 dimensions, using resurgent asymptotic analysis to find trans-series solutions which yield non-perturbative completion of divergent perturbative Kreimer-Connes Hopf-algebraic Dyson-Schwinger equations for anomalous dimension. This conformal is and has a real Lipatov instanton. In approach we having an intricate Borel singularity structure, with three distinct but resonant terms, each repeated infinite series. These expansions are terms renormalized coupling. The structure leads powers logarithmic at higher levels trans-series, analogous arising from interactions between instantons anti-instantons, purely formalism rather than semi-classical analysis.

Dyson Schwinger Equations: From Hopf algebras to Number Theory

We consider the structure of renormalizable quantum field theories from the viewpoint of their underlying Hopf algebra structure. We review how to use this Hopf algebra and the ensuing Hochschild cohomology to derive non-perturbative results for the short-distance singular sector of a renormalizable quantum field theory. We focus on the short-distance behaviour and thus discuss renormalized Gre...

The Measure from Schwinger-Dyson Equations

dt Jq) . (2) The ~ → 0 limit of Z[J ] is dominated by configurations near to the solutions of δS δq +J = 0. On the other hand, ~ → 0 corresponds to classical physics given by δI δq + J = 0, where I is the action. From this we see that S[q] = I[q] + ~ i M [q] . (3) M [q] is the measure term. This is as far as the usual functional formalism takes us — namely, there is no way to determine the meas...

Dyson - Schwinger Equations in Nonperturbativefield

The Dyson-Schwingerequation formalism is reviewed and its applicationto nonperturba-tive studies of gauge eld theories is dicussed. As a speciic illustration of the derivation and techniques we discuss strong coupling QED. A detailed discussion of renormalisation in this approach is presented. This is necessary to extend current numerical techniques for studying strong-coupling QED to the case ...

Chiral Symmetry Breaking from Dyson-schwinger Equations

I report on recent progress in the study of mass generation in non-abelian gauge theories, and concentrate on the origin of constituent masses in QCD. I argue that a consistent formalism has been developed to describe chiral symmetry breaking via multiplicatively renormalisable Dyson-Schwinger equations. Its main consequence is the existence of a critical value of the coupling beyond which mass...

Derivation of Dyson-Schwinger equations

Dyson-Schwinger equations, the equations of motion of Green functions, provide a non-perturbative description of quantum eld theories. Especially for the strong interaction they have been used very successfully in recent years. In this note their derivation is described. As examples the twopoint Dyson-Schwinger equation for a scalar theory and the ghost-gluon vertex Dyson-Schwinger equations of...
