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

A measurement of jet activity in the rapidity interval bounded by a dijet system is performed using pp collisions at 7 TeV recorded by the ATLAS detector in 2010. Events are vetoed if a jet with transverse momentum greater than 20 GeV is found between the boundary jet. The data are compared to NLO parton shower prediction from POWHEG, all order resummation prediction from HEJ, and LO predictions from PYTHIA, HERWIG++ and ALPGEN event generators
