Description

Within Basis light-front Quantization framework, we obtain the masses comparable to experiment and the light-front wave functions of $\Lambda_b$ and its isospin triplet baryons $\Sigma_b^+$, $\Sigma_b^0$ and $\Sigma_b^-$. Our prediction of their electromagnetic properties is in agreement with other theoretical calculations. Meanwhile their parton distribution functions (PDFs) are obtained with the gluon and the sea quark PDFs generated dynamically from the QCD evolution of the valence ones.
