We present data on multiple production of jets with transverse energies near 20 GeV in p¯p collisions at √s=1.8TeV. QCD calculations in the parton-shower approximation of PYTHIA and HERWIG and the next-to-leading order approximation of JETRAD are compared to the data for one, two, three, and four jet inclusive production. Transverse energy spectra and multiple jet angular and summed transverse-energy distributions are adequately described by the shower approximation while next-to-leading order calculations describe the data poorly.Received 19 July 2002DOI:https://doi.org/10.1103/PhysRevD.67.052001©2003 American Physical Society
