Abstract
© 2018, CERN for the benefit of the CMS collaboration.Events with no charged particles produced between the two leading jets are studied in proton-proton collisions at s=7TeV. The jets were required to have transverse momentum pTjet>40GeV and pseudorapidity 1.5 0.2 GeV in the interval - 1 < η< 1 between the jets are observed in excess of calculations that assume no color-singlet exchange. The fraction of events with such a rapidity gap, amounting to 0.5–1% of the selected dijet sample, is measured as a function of the pT of the second-leading jet and of the rapidity separation between the jets. The data are compared to previous measurements at the Tevatron, and to perturbative quantum chromodynamics calculations based on the Balitsky–Fadin–Kuraev–Lipatov evolution equations, including different models of the non-perturbative gap survival probability.
