On-Shell Recursion Relations for Effective Field Theories
Clifford Cheung, Karol Kampf, Jiri Novotny +2
We derive the first ever on-shell recursion relations for amplitudes in effective field theories. Based solely on factorization and the soft behavior of amplitudes, these recursion…
Non-renormalization Theorems without Supersymmetry
Clifford Cheung, Chia-Hsien Shen
We derive a new class of one-loop non-renormalization theorems that strongly constrain the running of higher dimension operators in a general four-dimensional quantum field theory.…
Simple Recursion Relations for General Field Theories
Clifford Cheung, Chia-Hsien Shen, Jaroslav Trnka
On-shell methods offer an alternative definition of quantum field theory at tree-level, replacing Feynman diagrams with recursion relations and interaction vertices with a handful…
