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 Bs0->J/Psi eta' and B0s->J/Psi pi+pi- are studied. The decay-width difference between the light and heavy mass eigenstates of the Bs0 meson is measured to be DeltaGamma_s = 0.087 \pm 0.012 \pm 0.009 ps-1, where the first uncertainty is statistical and the second systematic.

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 Bs0->J/Psi eta' and B0s->J/Psi pi+pi- are studied. The decay-width difference between the light and heavy mass eigenstates of the Bs0 meson is measured to be DeltaGamma_s = 0.087 \pm 0.012 \pm 0.009 ps-1, where the first uncertainty is statistical and the second systematic.
