We have studied tbar-t production using multijet final states in pbar-p collisions at a center-of-mass energy of 1.8 TeV, with an integrated luminosity of 110.3 pb(-1). Each of the top quarks with these final states decays exclusively to a…
With the advent of the Tevatron Run 2, the collider experiments, CDF and D0, have reestablished the top quark and the W and Z signals and have begun programs of precision measurements of top quark and electroweak properties. We will survey…
We review the search for the top quark conducted by the D-Zero collaboration using data from the Fermilab pbar-p collider. Based upon a preliminary analysis of an integrated luminosity of about 13.5 pb-1, we have searched for t-tbar…

We present details of a search for electroweak production of single top quarks in the electron+jets and muon+jets decay channels. The measurements use \~90 pb^-1 of data from Run 1 of the Fermilab Tevatron collider, collected at 1.8 TeV…
This letter presents results on the precision measurement of the top quark mass and a combination of the best CDF top mass measurements. A combination by the TevEWWG (Tevatron electroweak working group) of the best top mass results from CDF…
The mass of the top quark has been measured at Fermilab using the Tevatron ppbar collider to a precision of less than 1%. I discuss the individual measurements that go into this result and its impact on our understanding of the standard…
We present a combination of measurements of the top quark mass by the D0 experiment in the lepton+jets and dilepton channels. We use all the data collected in Run I (1992--1996) at $\sqrt s=1.8$ TeV and Run II (2001--2011) at $\sqrt s=1.96$…
Using the ZEUS detector at HERA, we have searched for heavy excited states of electrons, neutrinos, and quarks in $e^+p$ collisions at a center-of-mass energy of 300~GeV. With an integrated luminosity of 9.4~pb$^{-1}$, no evidence was found…

We present a measurement of tbar-t production using multijet final states in pbar-p collisions at a center-of-mass energy of 1.8 TeV, with an integrated luminosity of 110.3 pb(-1). The analysis has been optimized using neural networks to…
We summarize a search for the top quark with the Collider Detector at Fermilab (CDF) in a sample of $\bar{p}p$ collisions at $\sqrt{s}$= 1.8 TeV with an integrated luminosity of 19.3~pb$^{-1}$. We find 12 events consistent with either two…
