Abstract

Production and decay of a pair of bottom mesons, one charged and one neutral, have been observed in a 200-TeV cosmic-ray helium interaction in an emulsion chamber. Analysis of the event indicates that the charged meson decays most probably via a b quark transition, which would imply a nonzero Vb element in the Kobayashi-Maskawa matrix. The simplest decay scheme consistent with the data is B-Ds. The neutral decay is interpreted as B0D-e+. © 1990 The American Physical Society.
