The MIT Libraries is completing a major upgrade to DSpace@MIT. Starting May 5 2026, DSpace will remain functional, viewable, searchable, and downloadable, however, you will not be able to edit existing collections or add new material. We are aiming to have full functionality restored by May 18, 2026 but intermittent service interruptions may occur. Please email dspace-lib@mit.edu
with any questions. Thank you for your patience as we implement this important upgrade.

| dc.description.abstract | © 2019 The Author Decays of Bs0 and B‾0s mesons into J/ψπ+π− final states are studied in a data sample corresponding to 1.9 fb−1 of integrated luminosity collected with the LHCb detector in 13 TeV pp collisions. A time-dependent amplitude analysis is used to determine the final-state resonance contributions, the CP-violating phase ϕs=−0.057±0.060±0.011 rad, the decay-width difference between the heavier mass Bs0 eigenstate and the B0 meson of −0.050±0.004±0.004 ps−1, and the CP-violating parameter |λ|=1.01−0.06+0.08±0.03, where the first uncertainty is statistical and the second systematic. These results are combined with previous LHCb measurements in the same decay channel using 7 TeV and 8 TeV pp collisions obtaining ϕs=0.002±0.044±0.012 rad, and |λ|=0.949±0.036±0.019. | |
