Determination of $|V_{\mathrm{cb}}|$ using Bayesian analysis of the $B\to D^{\ast }\ell {\bar{\hat{I}}½}_{\ell }$ semileptonic decay width with four-loop QCD corrections

The Cabibbo-Kobayashi-Maskawa matrix element $|V_{\mathrm{cb}}|$ is an important Standard Model parameter, whose value can be determined by using the semi-leptonic decay $B\rightarrow D…
