Top Pair Production

Steve Ellis (University of Washington; Theory)
Steve Blusk (University of Rochester; CDF)

Charge: Total cross section (how well can it be measured and calculated); kinematical characteristics and spin correlations; the top-antitop invariant mass spectrum; sensitivity to unconventional three-gluon couplings, etc. The motivation and rewards of these studies.

******* SPECIAL NOTICE *******
Due to the commonality of some of the subjects, this session will be combined with the session on "Precision Measurements" for the discussions on gluon radiation in ttbar Events. This joint session will include the first 2 speakers, after which the two groups will separate into their respective subgroups.

Program
Saturday Morning, October 17

Joint "ttbar Pair Production" + "Precision Measurements" subgroups
