Euclidean Field Theory and Singular Classical Field Configurations
Euclidean field theory on four dimensional sphere is suggested for the study of high energy multiparticle production. The singular classical field configurations are found in scalar φ and SU(2) gauge theories and the cross section of 2→ n is calculated. It is shown, that the cross section has a maximum at the energy compared to the sphaleron mass. E-mail address: [email protected]
متن کاملEuclidean Field Theory
In this review, we consider Euclidean field theory as a formulation of quantum field theory which lives in some Euclidean space, and is expressed in probabilistic terms. Methods arising from Euclidean field theory have been introduced in a very successful way in the study of the concrete models of Constructive Quantum Field Theory. Euclidean field theory was initiated by Schwinger [1] and Nakan...
متن کاملFrom euclidean field theory to quantum field theory
In order to construct examples for interacting quantum field theory models, the methods of euclidean field theory have turned out to be a powerful tools since they make use of the techniques of classical statistical mechanics. Starting from an appropriate set of euclidean 3⁄4 -point functions (Schwinger distributions), a Wightman theory can be reconstructed by an application of the famous Oster...
متن کاملClassical Field Theory
a) Energy-momentum Based on Noether’s theorem, construct the energy-momentum tensor for classical electromagnetism from the above Lagrangian. Note that the usual procedure does not result in a symmetric tensor. To remedy that, we can add to T μν a term of the form ∂λK λμν , where K is antisymmetric in its first two indices. Such an object is automatically divergenceless, so T̂ μν = T μν + ∂λK λμ...
متن کاملEuclidean field theory on a sphere
This paper is concerned with a structural analysis of euclidean field theories on the euclidean sphere. In the first section we give proposal for axioms for a euclidean field theory on a sphere in terms of C*algebras. Then, in the second section, we investigate the short-distance behavior of euclidean field theory models on the sphere by making use of the concept of scaling algebras, which has ...
