Top Physics from Run 1 and Run 2 Prospects at CDF

We present a summary of top quark physics results from Run 1 at CDF using the Run 1 data sample of 106 pb$^{-1}$. In addition to the precursory measurements of the top quark mass and \ttbar cross section, we have performed a number of other analyses which test the consistency of the \ttbar data sample with the standard model (SM). Deviations from SM expectations could provide hints for new physics. We find that the data are consistent with the SM. While the Run 1 data are statistically limited, we have shown that the systematic uncertainties are under control and thus have layed the groundwork for higher precision tests of the SM in Run 2. This report describes the Run 1 top quark analyses and expectations and prospects for top quark measurements in Run 2.Comment: 3 page

Upsilon Decays at CLEO

Using data collected using the CLEO III detector, we present recent results on decays of the $\Upsilon(1S)-\Upsilon(3S)$ resonances. We report on three analyses. They are: (1) improved measurements of the muonic branching fraction of the $\Upsilon(1S)-\Upsilon(3S)$, (2) precision measurements of $\Upsilon(2S)$ and $\Upsilon(3S)$ photonic transitions, and (3) new measurements of $\Upsilon(1S)$ decays to charmonium final states.}]Comment: 4 pages, 5 figures.

Measurement of the Top Quark Mass

In this paper, we report on the most recent measurements of the top quark mass, performed by the CDF and D0 collaborations at the Fermilab Tevatron. The CDF collaboration has performed measurements of the top quark mass in three decay channels from which the top quark mass is measured to be 175.6 +- 6.8 GeV/c^2. The D0 collaboration combines measurements from two decay channels to obtain a top quark mass of 172.1 +- 7.1 GeV/c^2. Combining the measurements from the two experiments, assuming a 2 GeV/c^2 correlated systematic uncertainty, the measurement of the top quark mass at the Tevatron is 173.9 +- 5.2 GeV/c^2. This report presents the measurements of the top quark mass from each of the decay channels which contribute to this measurement.Comment: To be published in the 33rd proceedings of the Recontres de Moriond, Les Arcs, France, March 21-28, 1998. 6 pages, 3 figure

Design and Expected Performance of the BTeV RICH

The BTeV experiment is a b-physics experiment designed to conduct precision tests of the CKM description of CP violation and study rare processes involving bottom and charm hadrons. The experiment will be located in the C0 interaction region at the Fermilab Tevatron, and is intended to begin data-taking around 2007-2008. One of the most important elements of the BTeV spectrometer is the ring-imaging Cerenkov detector (RICH) which is used for particle identification. In this article we describe the BTeV RICH and present its expected performance.Comment: 5 pages, 5 figures. Proceedings of the RICH2002 Conference, Pylos, Greece, June 5-10, 200

Performance of a C4F8O Gas Radiator Ring Imaging Cherenkov Detector Using Multi-anode Photomultiplier Tubes

We report on test results of a novel ring imaging Cherenkov (RICH) detection system consisting of a 3 meter long gaseous C4F8O radiator, a focusing mirror, and a photon detector array based on Hamamatsu multi-anode photomultiplier tubes. This system was developed to identify charged particles in the momentum range from 3-70 GeV/c for the BTeV experiment.Comment: 28 pages, 23 figures, submitted to Nuclear Instruments and Method
