Michael Albrow (Fermilab)12/09/2014, 11:00Forward physics in hadron-hadron collisionsThe first observations of double pomeron exchange (DPE) reactions were in pp collisions at the CERN Intersection Storage Rings (ISR) in the early 1980’s, with C.M. energies up to 63 GeV. These were followed by many detailed studies at the SPS and at the Tevatron (fixed target), with lower C.M. energy but higher statistics and a variety of final state produced hadrons. I will give a...Go to contribution page

Prof. Mariusz Przybycien (AGH University of Science and Technology)12/09/2014, 11:20Forward physics in hadron-hadron collisionsPreliminary measurement of the Central Exclusive Production of the two oppositely charged pions produced in the process $pp\to pp \pi^+\pi^-$, obtained with the STAR detector at RHIC at \sqrt{s} = 200 GeV is presented. The Roman Pots were used to tag forward protons while pion pair tracks were reconstructed in the STAR Time Projection Chamber (TPC). Predictions of models based on Regge...Go to contribution page

Ms Maria Zurek (FZ Juelich, University of Cologne)12/09/2014, 11:40Forward physics in hadron-hadron collisionsWe have measured exclusive $\pi^{+}\pi^{-}$ production in proton-antiproton collisions at $\sqrt{s}=$0.9 and 1.96 TeV in the Collider Detector at Fermilab. We selected events with exactly two oppositely charged particles in $|\eta|<1.3$, with no other particles detected in $|\eta|<5.9$. The central $\pi^{+}\pi^{-}$ was required to have rapidity $|y|<1$. By requiring no other charged particles,...Go to contribution page

Prof. Gilvan Alves (CBPF/MCT)12/09/2014, 12:00Forward physics in hadron-hadron collisionsWe report on the CMS measurements of exclusive and diffractive processes, including the latest CMS measurements of exclusive and diffractive production of dijets, dimuons and vector bosons in pomeron- and photon-induced collisions in p-p at 7 TeV. The data are compared to various theoretical predictions.Go to contribution page

Dr Murilo Rangel (UFRJ)12/09/2014, 12:20Forward physics in hadron-hadron collisionsAn updated measurement of exclusive J/psi and psi(2S) vector meson production is presented. The forward reach of the LHCb detector is sensitive to the gluon PDF down to x=5E-6. The data are compared to predictions at LO and NLO order and to model that include saturation effects, which may become important at such low x-values. Comparisons are also made to photoproduction results from HERA and...Go to contribution page
