Top Quark Physics: Overview

In this presentation I will primarily focus on top quark physics but I will include a discussion of the W-boson mass and the possibility of discovering a light Higgs boson via associated production at the Tevatron.Comment: 15 pages, 12 figures, Latex, sprocl.sty presentation at the International Symposium on ``QCD Corrections and New Physics'' October 27-29, 1997 held at Hiroshima, Japa

Top Quark Production Dynamics

I review standard top quark production at the Fermilab Tevatron. The current theoretical understanding of the total cross section and many partial differential cross sections is presented. Studies on the effects of extra gluon radiation on the top quark mass determination are reviewed. The possibility of new mechanisms for $t\bar{t}$ production are also discussed.Comment: 8 RevTex pages, requires AIPBOOK style file, 20 figures appended as uuencoded file. Invited talk at the Xth International PbarP Workshop, Fermilab, IL, May 9-13, 199

Neutrinos: Theory and Phenomenology

The theory and phenomenology of neutrinos will be addressed, especially that relating to the observation of neutrino flavor transformations. The current status and implications for future experiments will be discussed with special emphasis on the experiments that will determine the neutrino mass ordering, the dominant flavor content of the neutrino mass eigenstate with the smallest electron neutrino content and the size of CP violation in the neutrino sector. Beyond the neutrino Standard Model, the evidence for and a possible definitive experiment to confirm or refute the existence of light sterile neutrinos will be briefly discussed.Comment: 15 pages, 10 figures, presentation at the "Nobel Symposium on LHC results", May 13-19, 2013 at Krusenberg, Uppsala, Swede

Top Quark Spin Correlations - Theory

The theoretical aspects of spin correlations in top quark pair production are briefly reviewed.Comment: 4 pages, 3 figures, proceedings for TOP201

Finite Width Effects in Top Quark Decays

Motivated by evidence that the top quark mass lies near the $bWZ$ threshold, we compute the decay rate for $t\rightarrow bWZ$ in the Standard Model, including the effects of the finite widths of the $W$ and $Z$ bosons. In the limit where the width effects are negligible, our results disagree with previously published calculations. We also examine the decay $t\rightarrow bWH$. Although the widths induce a sizable enhancement near threshold for both decays, we find that the rates are still too small to be observed in the present generation of experiments. This means that detection of either mode in one of these experiments would be a signal of new physics.Comment: 10 pages, Revtex, 3 uuencoded figures include
