Massive On-shell Splitting Functions in Spinor-Helicity Formalism
Yi-Ning Wang, Chao Wu, Jiang-Hao Yu
The authors develop an on‑shell spinor‑helicity framework for massive collinear splitting functions, deriving complete leading and subleading massive splitting kernels for all Stan…
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…
On-Shell Renormalization of Dim-8 SMEFT from Complete Amplitude Basis: I. Four-Fermion Operators
Chao Wu, Ming-Lei Xiao, Jiang-Hao Yu +1
We compute the complete one-loop renormalization group equations (RGEs) for all the four-fermion operators at dimension-8 Standard Model Effective Field Theory (SMEFT). We adopt th…
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…
