OPAL Measurements of Δmd and Search for CP and CPT Violation in the Bd System

Conference paper


Four measurements of Δm d from OPAL are presented, giving Δmd = 0.467 ± 0.022 −0.015 +0.017 ps−1

Using a time-dependent analysis, results on the CP and CPT violating parameters Re ∈B and Im δB were also obtained, and the parameters were found to be consistent with zero.
