Two-variable longitudinal distribution of the $Λ_{b}$ in a three-quark light-front model

Shuai Xu, Xiao-Nan Li

We determine a normalized two-variable longitudinal distribution of the $Λ_{b} = (u d) b$ baryon from a covariant three-quark light-front wave function. The scalar $u d$ channel is select…
