Extended Poincare Symmetry Dictates Massive Scattering Amplitudes

Yu-Han Ni, Yi-Ning Wang, Chao Wu +1

We identify an extended Poincare symmetry $I S O (2) \times I S O (3, 1)$ for on-shell massive scattering amplitudes, transforming under the $U (2)$ Little group symmetry. Thus the one-par…

Complete UV Resonances of the Dimension-8 SMEFT Operators

Hao-Lin Li, Yu-Han Ni, Ming-Lei Xiao +1

The effective field theory approach parameterizes the low energy behaviors of all possible ultraviolet (UV) theories in a systematic way. One of the most important tasks is thus to…
