Excited $\Omega$ hyperon in charmful ${\Omega }_b$ weak decays

Kai-Lei Wang, Juan Wang, Yu-Kuo Hsiao +1

We investigate the sextet $b$-baryon decay processes ${\Omega }_b\to J/\psi {\Omega }^{(\ast )}$,where ${\Omega }^{\ast }$ represents the $1P$-, $1D$- and $2S$-wave excited $\Omega$ hyperons in the spectroscopy. Using the c…
