Color-kinematics duality from the Bern-Kosower formalism

چکیده
Berends-Giele currents are fundamental building blocks for on-shell amplitudes in non-abelian gauge theory. We present a novel procedure to construct them using the Bern-Kosower formalism one-loop gluon amplitudes. Applying pinch of that suitable special case naturally obtained terms multi-particle fields and obeying colour-kinematics duality. As feedback we outline how polarisations field-strength tensors can be used significantly streamline procedure.

World-line approach to the Bern-Kosower formalism in two-loop Yang-Mills theory
Based on the world-line formalism with a sewing method, we derive the Yang-Mills effective action in a form useful to generate the Bern-Kosower-type master formulae for gluon scattering amplitudes at the two-loop level. It is shown that four-gluon (Φ type sewing) contributions can be encapsulated in the action with three-gluon (Φ type) vertices only, the total action thus becoming a simple expr...
متن کاملBern-Kosower rule for scalar QED.
We derive a full Bern-Kosower-type rule for scalar QED starting from quantum field theory: we derive a set of rules for calculating S-matrix elements for any processes at any order of the coupling constant. Gauge-invariant set of diagrams in general is first written in the worldline path-integral expression. Then we integrate over x(τ), and the resulting expression is given in terms of correlat...
متن کاملThe Structure of the Bern – Kosower Integrand for the N – Gluon Amplitude
An ambiguity inherent in the partial integration procedure leading to the BernKosower rules is fixed in a way which preserves the complete permutation symmetry in the scattering states. This leads to a canonical version of the BernKosower representation for the one-loop N – photon/gluon amplitudes, and to a natural decomposition of those amplitudes into permutation symmetric gauge invariant par...
متن کاملExact Combinatorics of Bern - Kosower - type Amplitudes for Two - Loop Φ 3 Theory
Counting the contribution rate of a world-line formula to Feynman diagrams in φ theory, we explain the idea how to determine precise combinatorics of Bern-Kosower-like amplitudes derived from a bosonic string theory for N -point two-loop Feynman amplitudes. In this connection we also present a method to derive simple and compact world-line forms for the effective action. PACS: 11.15.Bt; 11.55.-...
متن کاملSymmetry for Flavor-Kinematics Duality from an Action.
We propose a new representation of the nonlinear sigma model that exhibits a manifest duality between flavor and kinematics. The fields couple exclusively through cubic Feynman vertices which define the structure constants of an underlying kinematic algebra. The action is invariant under a combination of internal and spacetime symmetries whose conservation equations imply flavor-kinematics dual...
