Symmetry-preserving calculation of pion light-front wave functions

Zhao-Qian Yao, Zhen-Ni Xu, Yu-Yang Xiao +2

Poincaré-covariant Bethe-Salpeter wave functions are used to calculate light-front wave functions (LFWFs) of the pion, $\pi$, and an analogue state, ${\pi }_{s\bar{s}}$. The current masses…
