CPT Student Seminar: Spinor-helicity amplitudes and the CHY formalism
I will review a technique to obtain analytical spinor-helicity rational coefficients for loop amplitudes from floating-point numerical evaluations, with explicit examples for QCD processes. Afterwards, I will discuss the Cachazo-He-Yuan formalism for massless scattering. I will show how arbitrary-precision numerical solutions of the scattering equations lead to compact analytical tree-level amplitudes in a variety of theories, including the first complete set of five-point (DF)^2 amplitudes.
