BRST-driven cancellations and gauge invariant Green's functions

2004

We study a fundamental, all order cancellation operating between graphs of distinct kinematic nature, which allows for the construction of gauge-independent effective self-energies, vertices, and boxes at arbitrary order.

The effective neutrino charge radius in the presence of fermion masses

2005

Abstract We show how the crucial gauge cancellations leading to a physical definition of an effective neutrino charge radius persist in the presence of non-vanishing fermion masses. An explicit one-loop calculation demonstrates that, as happens in the massless case, the pinch technique rearrangement of the Feynman amplitudes, together with the judicious exploitation of the fundamental current relation J α ( 3 ) = 2 ( J Z + sin θ w 2 J γ ) α , leads to a completely gauge independent definition of the effective neutrino charge radius. Using the formalism of the Nielsen identities it is further proved that the same cancellation mechanism operates unaltered to all orders in perturbation theory.

JaxoDraw: A graphical user interface for drawing Feynman diagrams

2019

Abstract JaxoDraw is a Feynman graph plotting tool written in Java. It has a complete graphical user interface that allows all actions to be carried out via mouse click-and-drag operations in a WYSIWYG fashion. Graphs may be exported to postscript/EPS format and can be saved in XML files to be used for later sessions. One of JaxoDraw's main features is the possibility to create code that may be used to generate graphics output, thus combining the powers of with those of a modern day drawing ... Title of program: JaxoDraw Catalogue Id: ADUA_v1_0 Nature of problem Existing methods for drawing Feynman diagrams usually require some "hard-coding" in one or other programming or scripting language…
