TITLE Amplitude methods for BSM
ABSTRACT I will start describing how effective theories can be characterized by
on-shell amplitudes (instead of Lagrangians of fields). Later, I will show how amplitude methods allow to derive one-loop renormalization effects from just tree-level amplitudes, with no need of loop calculations.
I will show how this works for dimension-6 operators of the Standard Model, providing explicit examples of the simplicity, elegance and efficiency of the method.
