Minijet activity in high E_T jet events at the Tevatron

Abstract

Gluon bremsstrahlung in scattering events with high transverse momentum jets is expected to increase markedly with the hardness (sum E_T) of the primary event. Within perturbative QCD we estimate a probability of order unity to see additional minijets with E_T >~ 15 GeV in ``dijet'' events with sum E_T > 400 GeV. The veto of such minijets is a promising background rejection tool for the Higgs search at the LHC.
