Recent b-physics results from OPAL

Abstract

The most recent b-physics results from the OPAL experiment at LEP are reviewed. A measurement of semileptonic B meson decays to narrow orbitally-excited charm mesons is presented first, followed by a study of charm production in b-hadron decays. Here, B refers to B+ and B0 mesons and their charge conjugates, and b-hadron refers to the admixture of hadrons containing a b quark produced in electron-positron annihilations at \sqrt{s}= m_Z.Comment: 3 pages, 2 figures, LaTeX, epj style (included), Proceedings of the International Europhysics Conference on High Energy Physics EPS 2003 (July 17-23, 2003), Aachen, German
