摘要：

The distribution of the transverse energy in jets has been measured in p $($) over bar$$ p collisions at root s = 1.8 TeV using the DO detector at Fermilab. This measurement of the jet shape is made as st function of jet transverse energy in both the central and forward rapidity regions. Jets are shown to narrow both with increasing transverse energy and with increasing rapidity. Next-to-leading order partonic QCD calculations are compared to the data. Although the calculations qualitatively describe the data, they are shown to be very dependent on renormalization scale, parton clustering algorithm, and jet direction definition and they fail to describe the data in all regions consistently.
