Color Decomposition for Scattering Amplitudes
Analysis
This paper presents a method for systematically decomposing the color dependence of scattering amplitudes in gauge theories. This is crucial for simplifying calculations and understanding the underlying structure of these amplitudes, potentially leading to more efficient computations and deeper insights into the theory. The ability to work with arbitrary representations and all orders of perturbation theory makes this a potentially powerful tool.
Key Takeaways
- •Provides a method for decomposing the color dependence of scattering amplitudes.
