B and D Spectroscopy at LEP
Abstract
Results from the four LEP experiments ALEPH, DELPHI, L3, and OPAL on the spectroscopy of B and charmed mesons are presented. The predictions of Heavy Quark Effective Theory (HQET) for the masses and the widths of excited L=1 B mesons are supported by a new measurement from L3. A few Bc candidate eve nts have masses consistent with the recent CDF observation and the predictions. New results on Ddstar production and B -> Ddstar l nu are also presented. The evidence for a Dstarpr meson reported recently by DELPHI is not supported by OPAL and CLEO.
