Session 1: Diffraction and Central Exclusive Production II
- Lucian Harland-Lang (University of Oxford)
Recent results from the H1 and ZEUS collaborations will be presented. Topics will include cross sections for prompt photon production, J/psi and psi' production and rho and rho' production, a study of collective effects, and a fit to diffractive DIS data.
Inclusive single diffractive dissociation (pp->pX) is studied using data collected by the ATLAS experiment at the LHC. The intact proton is reconstructed and measured in the ALFA forward spectrometer, while charged particles from the dissociative system (X) are reconstructed and measured using the ATLAS inner tracking detector and calorimeters. Differential cross sections are presented as a...
Here we present overview of the results on diffractive and exclusive measurements with CMS only and CMS-TOTEM data.
Photon-induced processes in proton-proton interactions have become
recently very topical. The large energy at the LHC, when combined with
relatively large luminosity at run II, allows starting the exploration of such processes.
We discuss the production of $W^+ W^-$ pairs and $t \bar t$ quark-antiquark pairs in proton-proton collisions induced by two-photon fusion including, for
We present a partonic picture for diffractive onium - nucleus scattering from which the distribution of rapidity gap in a certain kinematic region can be deduced. This picture allows us to draw a parallel between diffractive dissociation and the genealogy of partonic evolution, the latter being essentially similar to a branching - diffusion process. In particular, we show that the rapidity ...
