Diffractive hard scattering

TL;DR: In this article, a measurement of the proton structure function was reported for momentum transfer squared Q^2 between 4.5 GeV^2 and 1600 GeV+2 and for Bjorken x between 1.8\cdot10^{-4} and 0.13 using data collected by HERA experiment H1 in 1993.

TL;DR: In this article, the authors discuss heavy quarkonium production through parton fragmentation, including a review of arguments for the factorization of high-p{T}$ particles into fragmentation functions for hadronic initial states.

TL;DR: HERA, the first electron-proton collider, has been delivering luminosity since 1992 as mentioned in this paper, and it is the natural extension of an impressive series of fixed-target lepton-nucleon scattering experiments.

TL;DR: In this paper, the authors derived properties of diffractive dissociation of virtual photons in the triple-pomeron regime and showed that the photonpomerons interactions can be described by the partonic structure function, which satisfies the conventional GLDAP evolution equations.

TL;DR: In this paper, it was shown that factorization holds at leading twist in the Drell-Yan cross section dσ/dQ2dy and related inclusive hadron-hadron cross sections.

TL;DR: In this article, a perturbative, non-scaling, QCD approach is used to calculate production cross sections for "naked" heavy flavour states in pp and p p collisions.

TL;DR: In this paper, the pseudorapidity distribution of charged tracks, produced in the fragmentation of the system X, is well described within the limits of cylindrical phase space, and the fragments of the X-system behave very similarly to the products of non-diffractive inelastic collisions at s = M.

TL;DR: In this article, it was shown that one can already expect measurable rates even for the production of two heavy flavour pairs from multigluon scatterings in double-pomeron exchange reactions at the CERN-SPS collider.
