Henriette Elvang | Effective Field Theories from Amplitudes
Показать описание
[ All Things EFT 4 | Oct 21, 2020 ] Henriette Elvang reviews the on-shell amplitudes approach to study and characterize effective field theories. Examples were given involving scalars, fermions, vectors, and gravitons. There were results about soft theorems in EFTs, soft bootstrap of `exceptional' EFTs, supersymmetry, and the efficiency of using on-shell matrix elements to classify higher-derivative operators.
