Results on soft gluon resummation and color coherence in {ital p{bar p}} collisions at {radical}{ital s}=1.8 TeV
- Department of Physics and Astronomy, Michigan State University, East Lansing, Michigan 48824, (United States)
We present two QCD studies based on data collected by the DO/ detector during the 1992{endash}1993 run and data recorded by the CDF detector during the 1988{endash}1989 run of the Fermilab Tevatron {ital p{bar p}} collider at a center of mass energy of {radical}{ital s}=1.8 TeV. The first study by the DO/ collaboration presents preliminary results on jet-jet angular decorrelation as a function of rapidity separation. This measurement is compared to HERWIG shower-level and JETRAD NLO parton-level Monte Carlo simulations. Data are also compared to predictions based on the techniques of Balitsky, Fadin, Kuraev, and Lipatov to resum soft gluon emissions which are expected to cause decorrelation of the produced jets. The second study demonstrates initial-to-final state color coherence effects by measuring the spatial correlations between soft and hard jets in multijet events. Both CDF results and DO/ preliminary measurements are presented and compared to several Monte Carlo simulations with different color coherence implementations. The DO/ data, which include both central and forward jets, are also compared to the predictions of JETRAD Monte Carlo. {copyright} {ital 1996 American Institute of Physics.}
