Abstract: (arXiv)
We present results for the strong widths corresponding to the ΣbΛbπ\Sigma_b\to \Lambda_b\, \pi and ΣbΛbπ\Sigma_b^{*}\to \Lambda_b\, \pi decays. We apply our model in Ref. Phys. Rev. D 72, 094022 (2005) where we previously studied the corresponding transitions in the charmed sector. Our non-relativistic constituent quark model uses wave functions that take advantage of the constraints imposed by heavy quark symmetry. Partial conservation of axial current hypothesis allows us to determine the strong vertices from an analysis of the axial current matrix elements.
