Abstract: (arXiv)
The derivation of Feynman rules for unparticles carrying standard model quantum numbers is discussed. In particular, this note demonstrates that an application of Mandelstam's approach to constructing a gauge-invariant action reproduces for unparticles the vertices one obtains through the usual minimal coupling scheme/ other non-trivial requirements are satisfied as well. This approach is compared to an alternative method that has recently been constructed by A. L. Licht.- coupling: minimal
- unparticle
- Feynman graph
- vertex function
- gauge field theory
