  Abstract Using a dataset corresponding to 9 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) -> J/psi eta' and B-s(0) -> 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 +/- 0.012 +/- 0.009 ps(-1), where the first uncertainty is statistical and the second systematic.
