Measurement of (Delta)m(sub d) using a probability based same-side tagger appliedto lepton + vertex events

摘要

A measurement (delta)m(sub d) is performed using inclusive lepton+vertex eventsat CDF. A probability based Same-Side Tagger was developed to tag the initial b-flavor of the B(sup 0)(sub d), which suppresses tagging on B-decay products. We (delta)m(sub d) = 0.42+/-0.09+/-0.03 ps(sup -1).
