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

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
colliders.Comment: 7 pages, Latex, uses aipproc.sty; plenary talk presented at Linear

Use and Conservation of the Biosphere: Proceedings of the Intergovernmental Conference of Experts on the Scientific Basis for Rational Use and Conservation of the Resources of the Bioshpere, Paris, 4-13 September 1968. Paris: United Nations Educational, Scientific and Cultural Organization, 1970. 272 pp. Paper, $6.00 (available in U.S.A. from Unipub, Inc., P.O. Box 433, New York, N.Y. 10016).
Excerpt: The Intergovernmental Conference of Experts on the Scientific Basis for Rational Use and Conservatiori of the Resources of the Biosphere was sponsored by UNESCO and attended by 326 delegates from 63 nations, 11 international organizations, and 14 nongovernmental organizations. For the purposes of discussion, the biosphere was defined as being that part of the planet earth in which life exists. The resources considered were largely restricted to living organisms; inorganic resources were included only insofar as they provide a medium for the support of plant and animal life. Oceanic resources were left to other international conferences for study
Gluon Radiation in Top Quark Production and Decay at an e^+ e^- Collider
We study the effects of gluon radiation on top production and decay processes
at an collider.The matrix elements are computed without any
approximations, using spinor techniques. We use a Monte Carlo event generator
which takes into account the infrared singularity due to soft gluons and
differences in kinematics associated with radiation in the production versus
decay process. The calculation is illustrated for several strategies of top
mass reconstruction.Comment: 9 pages, LaTeX, 6 postscript figures, uses aipproc.sty; presented at
