Amplitudes for massive vector and scalar bosons in spontaneously-broken gauge theory from the CHY representation
In the formulation of Cachazo, He, and Yuan, tree-level amplitudes for massless particles in gauge theory and gravity can be expressed as rational functions of the Lorentz invariants $k_a \cdot k_b$, $ε_a \cdot k_b$, and $ε_a \cdot ε_b$, valid in any number of spacetime dimensions. We use dimensional reduction of …
