Isgur-Wise functions for ${\mathbf{\Lambda }}_{\mathbf{b}}\to {\mathbf{\Lambda }}_{\mathbf{c}}\left({\frac{1}{2}}^{\pm }\right)$ transitions in the Bakamjian-Thomas Relativistic Quark Model

V. Morénas, A. Le Yaouanc, L. Oliver

We study the transitions ${\Lambda }_b\to {\Lambda }_c\left({\frac{1}{2}}^{\pm }\right)$ in the Bakamjian-Thomas (BT) relativistic quark model formalism, which describes hadrons with a fixed number o…
