Form factors and weak decays of $\Lambda_b\to\Lambda_c^*(2595)$ and $\Xi_b\to\Xi_c^*(2790)$

In this article, we reanalyze the mass and pole residue of $\Lambda$-type singly heavy baryons with spin-parity $J^P=1/2^{\pm}$ using two-point QCD sum rules. Then, we investigate the electroweak transition form factors of $\Lambda_b\to\Lambda^*_c(2595)$ and $\Xi_b\to\Xi^*_c(2790)$ within the framework of three-point Q...
