Measurement of the B0 s → µµ effective lifetime with the ATLAS detector ATLAS Collaboration
Abstract
This paper reports the frst ATLAS measurement of the B0 s → µµ efective lifetime. The measurement is based on the data collected in 2015–2016, amounting to 26.3 fb−1 of 13 TeV LHC proton-proton collisions. The proper decay-time distribution of 58 ± 13 background-subtracted signal candidates is ft with simulated signal templates parameterised as a function of the B0 s efective lifetime, with statistical uncertainties extracted through a Neyman construction. The resulting efective measurement of the B0 s → µµ lifetime is 0.99+0.42 −0.07 (stat.) ± 0.17 (syst.) ps and it is found to be consistent with the Standard Model.
