abstract

  • We report the observations of the decays [Formula Presented] and [Formula Presented] in [Formula Presented] collisions at a center-of-mass energy of 1.8 TeV using a [Formula Presented] data sample recorded by the Collider Detector at Fermilab. We also reconstruct the decays [Formula Presented] and [Formula Presented] and measure the six ratios of branching fractions of these four decays. The relative branching-fraction results are shown to be consistent with phenomenological factorization calculations of hadronic [Formula Presented]-meson decays. We use the world-average branching fraction [Formula Presented] to derive [Formula Presented] [Formula Presented] and [Formula Presented] where the first and second uncertainties are statistical and systematic, respectively. © 1998 The American Physical Society.
