Talk by Rick Field presented at the QCD Meeeting March 25, 1999
Study the CDF "Min-Bias" Data with the goal of finding a Monte-Carlo Generator that will fit
the data. Would like to describe (approximately) all the features of the entire inelastic ("hard core")
cross section (low PT and high PT)!
Look at the data (plot many observables) and compare to
Herwig and Isajet and Pythia.
For now consider only charged particles in the region,
PT > 0.5 GeV |eta| < 1, where efficiency is good.
In this talk I will concentrate on Jets ("Jet" = circular region).
Plot Distributions:
PTjet1 (connect to Jet20 data).
Look at PTjet1 dependence (plot averages versus PTjet1):
PTmax, Njet, NchgJet1, PTjet2, PTjet3, JetSize, etc..
Look at Jet Development as a Function of PTjet1:
NchgJet1, Jet Size, N-flow and PT-flow relative to Jet1 direction, "Fragmentation Functions".
Transparencies are available (30 pages) as a zipped postscript file (PS)
or as an Adobe Acrobat file (PDF).
