Lambda_b \rightarrow \Lambda_c^{\ast}$ at $1\,/\,m_c^2$ heavy quark order
We systematically compute the $\Lambda_b(p, s_b) \to \Lambda_c(2595)^+$ and $\Lambda_b(p, s_b) \to \Lambda_c(2625)^+$ form factors within the Heavy Quark Effective Theory (HQET) framework including $\mathcal{O}(1/m_c^2)$. Besides taking into account the Standard Model-like vector and axial contribut...

| description | We systematically compute the $\Lambda_b(p, s_b) \to \Lambda_c(2595)^+$ and
$\Lambda_b(p, s_b) \to \Lambda_c(2625)^+$ form factors within the Heavy Quark
Effective Theory (HQET) framework including $\mathcal{O}(1/m_c^2)$. Besides
taking into account the Standard Model-like vector and axial contributions, we
further determine tensor and pseudo-tensor form factors. Our work constitutes a
step forward with respect to previous analyses allowing for a comprehensive
study of the matrix element parametrisation stemming from the HQET formalism.
Finally, we demonstrate that the resulting form factors agree well with lattice
Quantum Chromodynamics (LQCD) determinations stressing the need and relevance
of the newly derived $1/m_c^2$ corrections. |
