Available in PDF, EPUB and Kindle. Book excerpt: We present a new expected upper limit of the rare decay branching ratio B{sub s} →??− using about 5 fb−1 of Run II data collected with the D0 detector at the Tevatron. When setting limits on the branching ratio, selected events are normalized to reconstructed B{sup {+-}} → J/?K{sup {+-}} events in order to decrease the systematic uncertainty. The resulting expected upper limit is?(B{sub s} →?+?−) = 4.3(5.3) x 10−8 at the 90% (95%) C.L.
