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 B0s → J/ψ η′ and B0s → J/ψ π+ π− are studied. The decay-width difference between the light and heavy mass eigenstates of the B0s meson is measured to be ΔΓs = 0.087 ± 0.012 ± 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 B0s → J/ψ η′ and B0s → J/ψ π+ π− are studied. The decay-width difference between the light and heavy mass eigenstates of the B0s meson is measured to be ΔΓs = 0.087 ± 0.012 ± 0.009 ps^−1, where the first uncertainty is statistical and the second systematic.
