Abstract:

We present a detailed description of a search for anomalous production of missing ET (Slashed E signT), jets, leptons (e, μ, τ), b quarks, or additional photons in events containing two isolated, central (|η|<1.0) photons with ET>12 GeV. The results are consistent with standard model expectations, with the possible exception of one event that has, in addition to the two photons, a central electron, a high-ET electromagnetic cluster, and large Slashed E signT. We set limits using two specific SUSY scenarios for production of diphoton events with Slashed E signT. ©1999 The American Physical Society.

Abstract:

We present a measurement of Z0 boson and Drell-Yan production cross sections in p̄p collisions at √s =1.8TeV using a sample of 107 pb-1 accumulated by the Collider Detector at Fermilab. The Drell-Yan cross section is measured in the mass range of Mμμ>40GeV/c2. We compare the measurements with the predictions of quantum chromodynamics in both leading order and next-to-leading order, incorporating the recent parton distribution functions. The measurements are consistent with the standard model expectations. ©1999 The American Physical Society.

Abstract:

Bd0-B̄d0 oscillations are observed in "self-tagged" samples of partially reconstructed B mesons decaying into a lepton and a charmed meson collected in pp̄ collisions at √s=1.8 TeV. A flavor tagging technique is employed which relies upon the correlation between the flavor of B mesons and the charge of a nearby particle. We measure the flavor oscillation frequency to be Δmd=0.471-0.068+0.078±0.034 ps-1. The tagging method is also demonstrated in exclusive samples of Bu+→J/ψK+ and Bd0→J/ψK*0(892), where similar flavor-charge correlations are observed. The tagging characteristics of the various samples are compared with each other, and with Monte Carlo simulations.
