Study of dijet events with a large rapidity gap between the two leading jets in pp collisions at √s=7TeV

Events with no charged particles produced between the two leading jets are studied in proton-proton collisions at √s = 7 TeV. The jets were required to have transverse momentum p jet T > 40 GeV and pseudorapidity 1.5 < |ηjet| < 4.7, and to have values of ηjet with opposite signs. The da...
