Visualizations of exclusive central diffraction

Central jet production as a probe of the perturbative formalism for exclusive diffraction

We propose a new variable, Rj , in order to identify exclusive double-diffractive high ET dijet production. The variable Rj is calculated using the transverse energy ET and pseudorapidity of the jet with the largest ET . For a purely exclusive event the value of Rj → 1, if we were to neglect hadronisaton and the detector resolution effects. To illustrate the expected Rj-distribution we also com...

A Study of Central Exclusive Production

political economy of china in central asia

this research is about the political economy of china in central asia. in this research the political & economic interactions affected on chinas political economy in central asia are examined. chinas goal of presence in central asia including political-security, economic and energy goals is described in one part. in another part, the trade relations between china and central asian countries ar...

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...

Diffraction, Exclusive Processes, and Proton Structure in Three Dimensions *

I briefly review how a three-dimensional picture of parton dynamics is rendered in the impact parameter representation, applied to generalized parton distributions and to the dipole picture of high-energy scattering. 1 The impact parameter representation Processes like deeply virtual Compton scattering, elastic meson production, and hard diffraction tell us about the spatial distribution of qua...
