Current Topics in Dø B-physics

The Tevatron, Fermilab’s pp 1.96 GeV/c C.M. Collider, has recently reached a delivered total of 1 fb of integrated luminosity to its two multi-purpose detectors, DØ and CDF, during the current data taking period known as RunII. Initial difficulties with beam stability were efficiently corrected during a shutdown in late 2003, and since then the Tevatron complex has operated remarkably well, with impressive recovery during 2004 and matching its luminosity design goals in 2005 [1]. The DØ detector has been steadily accumulating good quality data throughout RunII with luminosity recording efficiencies now approaching the 90% mark [2]. This article presents an overview of selected DØ studies in B Physics, with emphasis on the most recent results, many of which are still preliminary. Specific analyses are covered in more detail elsewhere in these proceedings.
