Measurement of [formula presented] flavor oscillations using jet-charge and lepton flavor tagging in [formula presented] collisions at [formula presented]

Journal Article

We present a measurement of the mass difference (Formula presented) for the (Formula presented) meson and the statistical power of the b flavor tagging methods used. The measurement uses (Formula presented) of data from (Formula presented) collisions at (Formula presented) collected with the CDF detector. An inclusive lepton trigger is used to collect a large sample of B hadron semileptonic decays. The mass difference (Formula presented) is determined from the proper time dependence of the fraction of B hadrons that undergo flavor oscillations. The flavor at decay is inferred from the charge of the lepton from semileptonic B decay. The initial flavor is inferred by determining the flavor of the other B hadron produced in the collision, either from its semileptonic decay (soft-lepton tag) or from its jet charge. The measurement yields (Formula presented), where the first uncertainty is statistical and the second uncertainty is systematic. The statistical powers (Formula presented) of the soft-lepton and jet-charge flavor taggers are (Formula presented) and (Formula presented), respectively. © 1999 The American Physical Society.
