Talk by Rick Field presented at the QCD Meeeting June 18, 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
MBR and Herwig and Isajet and Pythia 6.115 and Pythia 6.125 and Pythia (no multiple scattering) and Pythia 4097 (parameters set to values in CDF Note #4097).
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 the event shapes and study how charged particles are distributed relative to the direction of the leading jet ("Jet" = circular region).
Look at the Nchg-Flow at PTsum-Flow relative to the leading jet direction.
Look at PTjet1 dependence (plot averages versus PTjet1):
"Toward" Nchg, "Transverse" Nchg, "Away" Nchg, "Toward" PTsum, "Transverse" PTsum, "Away" PTsum.
Transparencies are available (24 pages) as a zipped postscript file (PS)
or as an Adobe Acrobat file (PDF).
Send comments, suggestions, etc.
