Top Quark Physics: Summary

This talk summarizes recent progress in top quark physics studies for high energy linear electron-positron colliders as presented at the LCWS2000 Workshop at Fermilab. New results were presented for top pair production at threshold and in the continuum, as well as for top production at $\gamma\gamma$ colliders.Comment: 7 pages, Latex, uses aipproc.sty; plenary talk presented at Linear Collider Workshop 2000, Fermilab, Batavia, IL, Oct. 24--28, 200

Gluon Radiation in Top Production and Decay at Lepton Colliders

In this talk we discuss gluon radiation in top production and decay. After reviewing results for hadron colliders we consider soft gluon radiation at lepton colliders and present gluon distributions that are potentially sensitive to production-decay interference effects.Comment: 8 pages including 4 figures, LaTeX; talk presented at the Workshop on Physics at the First Muon Collider and at the Front End of a Muon Collider, Batavia, IL, Nov. 6--9, 199

BFKL Physics in Jet Production at e+e- colliders

Virtual photon scattering in $e^+e^-$ collisions can result in events with the electron-positron pair at large rapidity separation with hadronic activity in between. The BFKL equation resums large logarithms that dominate the cross section for this process. We report here on a Monte Carlo method for solving the BFKL equation that allows kinematic constraints to be taken into account and show results for $e^+e^-$ collisions.Comment: 3 pages, Latex, talk presented at the 2000 Meeting of the Division of Particles and Fields of the APS, Columbus, OH, August 9--12, 200

Progress Towards a Generator for BFKL Physics

In certain regions of phase space in jet production, large logarithms can arise which are resummed by the BFKL equation. Linear colliders can potentially be excellent places to study BFKL effects in jet production. We discuss an approach to BFKL calculations which incorporates kinematic effects explicitly and can be implemented in an event generator.Comment: 4 pages including 2 figures, Latex, uses epsfig, aipproc.sty; talk presented at Linear Collider Workshop 2000, Fermilab, Batavia, IL, Oct. 24--28, 200
