| Abstract | Inclusive semi-leptonic decays of 𝐵 mesons are an excellent avenue for the study of B\bar{B} mixing, given their large branching fraction. In this talk, we present the measurement of the time integrated mixing parameter, 𝜒𝑑, using data collected by the Belle II detector. The Belle II experiment is located at the SuperKEKB laboratory in Tsukuba, Japan where electron-positron collisions at the Υ(4𝑆) energy yield a large number of B\bar{B} events. The mixing parameter 𝜒𝑑 is determined by examining the charge of reconstructed lepton pairs in 𝐵→𝑋ℓ𝜈 events. The result is based on 74 𝑓𝑏−1 of Belle II reprocessed data. |
