arXiv preprint arXiv:2310.12649, 2023•arxiv.orgUsing a dataset corresponding to $9~\mathrm {fb}^{-1} $ of integrated luminosity collected
with the LHCb detector between 2011 and 2018 in proton-proton collisions, the decay-time
distributions of the decay modes $ B_s^ 0\rightarrow J/\psi\eta'$ and $ B_s^ 0\rightarrow
J/\psi\pi^{+}\pi^{-} $ are studied. The decay-width difference between the light and heavy
mass eigenstates of the $ B_s^ 0$ meson is measured to be $\Delta\Gamma_s= 0.087\pm
0.012\pm 0.009\,\mathrm {ps}^{-1} $, where the first uncertainty is statistical and the second …
