Central exclusive dijet production at the Tevatron
We present a review of central exclusive dijet production in p̄p collisions, where the proton and antiproton emerge intact, and only two jets of transverse energy above a certain threshold are present in the final state. The results are published in two papers by the Collider Detector at Fermilab (CDF) Collaboration, a PRL (2000) and a PRD (2008), based on data collected at √ s = 1.8 TeV and 1.9...
متن کاملCentral Exclusive Production at the LHC
The idea to install detectors far from the interaction point at CMS and/or ATLAS with the capacity to detect protons scattered through small angles has gained a great deal of attention in recent years and the report presented in [1] constitutes a significant milestone on the road to CEP physics at the LHC. In this talk, I should like to focus attention in particular on Higgs boson production, a...
متن کاملCentral Exclusive Production at the Tevatron
In CDF we have observed several exclusive processes: γγ → e+e− and μ+μ−, γ + IP → J/ψ,ψ(2S), and IP + IP → χc. The cross sections agree with QED, HERA photoproduction data, and theoretical estimates of gg → χc with another gluon exchanged to screen the color. This observation of exclusive χc, together with earlier observations of exclusive dijets and exclusive γγ candidates, support some theore...
متن کاملCentral exclusive production of longlived gluinos at the LHC
We examine the possibility of producing gluino pairs at the LHC via the exclusive reaction pp → p+ g̃g̃ + p in the case where the gluinos are long lived. Such long lived gluinos are possible if the scalar super-partners have large enough masses. We show that it may be possible to observe the gluinos via their conversion to R-hadron jets and measure their mass to better than 1% accuracy for masses...
متن کاملExclusive central production of dijets at hadronic colliders
We critically re-examine the calculation of central production of dijets in quasi-elastic hadronic collisions. We find that the process is not dominated by the perturbative contribution, and discuss several sources of uncertainties in the calculation.
