0 QED in the Worldline Formalism
A survey is given of applications of the “string-inspired” worldline formalism to the computation of amplitudes and effective actions in QED. INTRODUCTION: QED IN FIRST QUANTIZATION The “worldline” or “string-inspired” formalism is an alternative to the usual second-quantized formalism in quantum field theory based on relativistic particle path integrals. Although it was invented by Feynman [1,...
متن کاملYukawa Couplings for the Spinning Particle and the Worldline Formalism
We construct the world-line action for a Dirac particle coupled to a classical scalar or pseudo-scalar background field. This action can be used to compute loop diagrams and the effective action in the Yukawa model using the world-line path-integral formalism for spinning particles. e-mail address [email protected] e-mail address [email protected] e-mail ad...
متن کاملPinched Gluon Vertex Operator in Super Worldline Formalism
We reformulate, using super worldline formalism, the pinched gluon vertex operator proposed by Strassler. The pinched vertex operator turns out to be the product of two gluon vertex operators with the insertion of δ-function which makes the super distances between them zero. Thus the pinch procedures turn out to be nothing but the insertions of δ-function. Applying our formulation to two-loop d...
متن کاملExploiting Symmetry in Tensors for High Performance
Symmetric tensor operations arise in a wide variety of computations. However, the benefits of exploiting symmetry in order to reduce storage and computation is in conflict with a desire to simplify memory access patterns. In this paper, we propose Blocked Compact Symmetric Storage wherein we consider the tensor by blocks and store only the unique blocks of a symmetric tensor. We propose an algo...
