A measurement of ∆Γs

Aaij, R. ; Ruiz-Vidal, Joan LU and Zunica, G. (2024) In Journal of High Energy Physics 2024(5).
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 Bs 0→J/ψη′ and Bs 0→J/ψπ+π− are studied. The decay-width difference between the light and heavy mass eigenstates of the Bs 0 meson is measured to be ∆Γs = 0.087 ± 0.012 ± 0.009 ps−1, where the first uncertainty is statistical and the second systematic. © The Author(s) 2024.
