چکیده
Top quark production at the Fermilab Tevatron probes very high mass scales, O(500 GeV ), and therefore is sensitive to new physics at this scale. Hence, it is important that we studied this process with high precision and compare the results with the standard model predictions. Also the top quark mass along with the W-boson mass can be used as an indirect measurement of the Higgs boson mass or even demonstrate the failure of the standard model. Therefore we must measure the top quark mass with the greatest precision possible with the events available to us. Here I review the status of the cross section calculations for top quark production not only for the total cross section but also for the shape of the various distributions associated with the production. For the kinematic measurement of the top quark mass the effects of extra gluon radiation are important for precision measurements. I will discuss the status of our understanding of this extra radiation. Finally, I will present a few of the possibilities for new physics that can dramatically change top quark production not only in total rate but also in the shape of the kinematic distributions.

The agreement of electroweak measurements with theory places limits on the masses of the top quark and the W boson. It is shown how these limits arise and what constraints various measurements (particularly a top quark mass determination) would provide on the theory. The degree to which present and future measurements can constrain the Higgs boson mass is examined.

In technicolor theories a large radiative correction to the Zbb vertex generally emerges, because of the large top quark mass and SU (2) L gauge symmetry. The correction can give us an explanation for the deviation of the experimental value of R b ≡ Γ b /Γ h from the standard-model prediction. However, generally the T parameter becomes unacceptably large. We show that in the one-family technico...

The polarization dependent momentum distributions of top quarks and their decay products are calculated for t ¯ t production at future e + e − colliders with polarized beams. The Green function formalism is applied to this reaction near energy threshold. The Lippmann–Schwinger equations for the S-wave and P-wave Green functions are solved numerically for the QCD chromostatic potential given by ...

We give a review of modern theoretical understanding of the problem of thermal phase transition in QCD. The existence or non-existence of such transition depends on the nature of the gauge group, the number of light quark flavors , and on the value of quark masses. Numerical lattice measurements indicate that the phase transition does not occur for the experimentally observed values of quark ma...
