We investigate the effect of soft gluon radiations on azimuthal angle correlation between total and relative momenta two jets in inclusive exclusive dijet processes. show that final state induces a sizable $\mathrm{cos}(2\ensuremath{\phi})$ anisotropy due to emissions near jet cones. The phenomenological consequences this observation are discussed for various collider experiments, including dif...

on behalf of the ATLAS and CMS Collaborations The LHC experiments provide an unprecedented coverage in pseudo-rapidity. This advantage and high LHC luminosity allow for broad studies of central exclusive production (CEP) processes such as exclusive production of ϒ, di-leptons, di-photons and di-jets. Finally, with the proposed near beam detectors (FP420 and FP220) the exclusive Higgs and SUSY s...

In the Collider Detector at Fermilab, CDF, we have measured central exclusive production, p + p̄ → p + X + p̄, where X is a pair of leptons or photons and nothing else. In this talk I focus on central masses M(X) > 8 GeV/c. We measured QED production γγ → ee, μμ up to M(X) = 75 GeV/c, and candidates for photoproduction of Upsilons, γIP → Y (1S), Y (2S), Y (3S). I report a search for exclusive pho...
