Complete UV Resonances of SMEFT Dim-9 Operators for Short-range Neutrinoless Double Beta Decay
Hao-Lin Li, Yu-Han Ni, Ming-Lei Xiao +2
We present a systematic classification of tree-level ultraviolet (UV) completions for dimension-nine SMEFT operators relevant to short-range neutrinoless double beta decay. Using t…
Massless-Massive Amplitude Correspondence II: Constructive Massive Amplitudes in Standard Model
Yu-Han Ni, Chao Wu, Jiang-Hao Yu
In the minimal helicity-chirality formalism, we systematically construct higher-point massive amplitudes from the fundamental building blocks: the contact three-point and four-poin…
Massless-Massive Amplitude Correspondence I: Helicity-chirality Matching and On-shell Higgsing
Yu-Han Ni, Chao Wu, Jiang-Hao Yu
In this work, the massless-massive correspondence for the on-shell scattering amplitudes is constructed so the massive amplitudes could inherit advantageous techniques developed in…
Massive Helicity-Chirality Spinor Formalism from Massless Amplitudes with On-shell Mass Insertion
Yu-Han Ni, Yi-Ning Wang, Chao Wu +1
We introduce a helicity-chirality spinor formalism to describe scattering amplitudes for particles of any masses and spins. The massive spin-spinors introduced by Arkani-hamed-Huan…
Extended Poincare Symmetry Dictates Massive Scattering Amplitudes
Yu-Han Ni, Yi-Ning Wang, Chao Wu +1
We identify an extended Poincare symmetry for on-shell massive scattering amplitudes, transforming under the 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…
