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…
