Central exclusive production in QCD

Exclusive production of dijets in QCD

We study in a framework of QCD collinear factorization the processes of a pion and a photon diffraction dissociation into two jets. The structure of non-factorizable contributions is discussed. We argue that coherent production of hard dijets by linearly polarized real photons can provide direct evidence for chirality violation in hard processes, the first measurement of the magnetic susceptibi...

Exclusive Production of Vector Mesons in Qcd

We compare results of our studies [1,2] on vector meson production within the QCD factorization at next-to-leading order with HERA data. 1 Introduction The exclusive vector meson V electro-and photo-productions in photon-proton collisions , γ p → V p, are the subject of HERA collider experiments. The primary motivation for the interests in these processes, both for the light ρ−meson electro-pro...

Exclusive Qcd

I give a brief introduction to the physics of generalized parton distributions and distribution amplitudes. I then report on the status of the calculation of radiative corrections for the exclusive processes where these quantities occur.

A Study of Central Exclusive Production

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...
