Measurement of dijet production with a veto on additional central jet activity in pp collisions at √s = 7TeV using the ATLAS detector

A measurement of jet activity in the rapidity interval bounded by a dijet system is presented. Events are vetoed if a jet with transverse momentum greater than 20GeV is found between the two boundary jets. The fraction of dijet events that survive the jet veto is presented for boundary jets that are...

description	A measurement of jet activity in the rapidity interval bounded by a dijet system is presented.
