TL;DR: In this paper, the charged-$B$ mass is 5270.0 MeV and the neutral-$B $ mass was 5274.5 MeV. The charged/$B$-meson decays to final states consisting of a ${D}^{0}$ or ${D]^{*\ifmmode\pm\else\textpm\fi{}}$ and one or two charged pions have been observed.

TL;DR: In this article, an enhancement has been observed in the inclusive cross section for direct single electrons produced in e/sup +/e/sup -/ annihilation at the UPSILON(4S), interpreted as evidence for a new weakly decaying particle.
Journal ArticleDOI

TL;DR: In this paper, the authors measured exclusive meson electroproduction at the Cornell Wilson Synchrotron and found that the width of the forward meson diffraction peak increases rapidly as the lifetime of the intermediate hadron states decreases below $c.
