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…
Identifying CP Basis Invariants in SMEFT
Neda Darvishi, Yining Wang, Jiang-Hao Yu
Building on our automated framework that uses ring diagrams for classifying CP basis invariants [Phys. Rev. D 108, 115030 (2023)], this paper broadens the application of the method…
Constructive Heavy Particle Effective Theory with Nonlinear Poincaré Symmetry
Yong-Kang Li, Yi-Ning Wang, Jiang-Hao Yu
We develop a constructive heavy particle effective theory (HPET) through the nonlinear realization of the spontaneously broken Poincaré symmetry $R^{3,1} \rtimes SO(3,1) \rightarr…
