Standard Model Effective Field Theory from On-shell Amplitudes

Apr 16, 2019, 9:00 AM


Jing Shu (ITP Beijing)


We present a general method of constructing unfactorizable on-shell amplitudes (amplitude basis), and build up their one-to-one correspondence to the independent and complete operator basis in effective field theory (EFT). We apply our method to the Standard Model EFT, and identify the amplitude basis in dimension 5 and 6, which correspond to the Weinberg operator and operators in Warsaw basis except for some linear combinations.
