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…
Covariant Spinor Formalism for Multipole Expanded Form Factor
Hong Huang, Tuo Tan, Yi-Ning Wang +1
We present a systematic technique for constructing Lorentz covariant orbital-spin () bases for matrix elements of local operators and the associated form factors, thereby exten…
Covariant canonical-spinor amplitudes for partial wave analysis
Hong Huang, Yi-Ning Wang, Jiang-Hao Yu
We propose a covariant orbital-spin () decomposed amplitude for the partial wave analysis using the massive spinor-helicity formalism. First we review the traditional- meth…
Systematic Operator Construction for Non-relativistic Effective Field Theories: Hilbert Series versus Young Tensor
Yong-Kang Li, Yi-Ning Wang, Jiang-Hao Yu
This work establishes a systematic framework for operator construction in the non-relativistic effective field theory, incorporating both the three dimensional Euclidean symmetry a…
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…
