GLUON RADIATION-PATTERNS IN HADRONIC COLLISIONS

The radiation pattern of soft gluons in hard scattering events is sens itive to the underlying color structure. Two examples are discussed: t he production of rapidity gaps in dijet events at the Tevatron and hea vy Higgs production via weak boson fusion at the LHC. A minijet veto f or weak boson scattering at the LHC makes use of the different angular distributions and momentum scales of gluon emission in signal and bac kground processes. It is a promising Higgs search tool.
