Diffraction in hadron-hadron collisions (phenomenology/theory)

Low missing mass (resonance region) single- and double proton diffraction dissociation is studied with emphasis on the LHC data. Regge-pole factorization, duality relations and unitarity bounds are discussed.

Diffraction in hadron-hadron collisions (phenomenology/theory)

Analysis of the new experimental data obtained by the TOTEM and ATLAS Collaborations at LHC at \sqrt{s} = 7 and 8 TeV at small momentum transfer is presented. Some contradictions in the obtained sizes of the total cross sections are analyzed. The impact of the different assumptions on the extraction of the parameters of the elastic scattering amplitude, especially on the size of the total...

Diffraction in hadron-hadron collisions (phenomenology/theory)

The amplitude for $\gamma p \to V p$, where $V$ is a $J/\psi$ or $\Upsilon$ ground state or excited vector meson, is calculated in a pQCD $k_{T}$-factorization approach. We use this amplitude to predict the cross section for exclusive photoproduction of $J/\psi, \psi'$ mesons in proton-proton collisions. Calculations are performed for a variety of unintegrated gluon distributions, and...
