Minijet veto: a tool for the heavy Higgs search at the LHC
Authors
Abstract
The distinct color flow of the process leads to suppressed radiation of soft gluons in the central region, a feature which is not shared by major background processes like production or . For the leptonic decay of a heavy Higgs boson, , it is shown that these backgrounds are typically accompanied by minijet emission in the 20--40 GeV range. A central minijet veto thus constitutes a powerful background rejection tool. It may be regarded as a rapidity gap trigger at the semihard parton level which should work even at high luminosities.
