Book Description
We present results on measurements of jet shapes and jet azimuthal decorrelation from {bar p}P collisions at (square root)s = 1.8 TeV using data collected during the 1992-1993 run of the Fermilab Tevatron. Jets are seen to narrow both with increasing Awe {sub TTY} and increasing rapidity. While HERWIG, a puritan shower Monte Carlo, predicts slightly narrower jets, it describes the trend of the data well; NO CD described qualitative features of the data but is sensitive to both renormalization scale and jet definitions. Jet azimuthal decorrelation has been measured out to five units of pseudorapidity. While next-to-leading order CD and a leading-log approximation based on BFKL resummation fail to reproduce the effect, HERWIG describes the data well.
