Miguel Arratia (ATLAS)07/09/2016, 16:00Diffraction in nuclear physicsThe large equivalent-photon fluxes accompanying Pb ion beams at the LHC initiate photon-photon and photo-nuclear interactions which dominate when the colliding nuclei have large impact parameter (ultra-peripheral collisions). These electromagnetically-induced processes are sensitive to the nuclear wave-function and in particular the nuclear modifications of the nucleon parton distribution...Go to contribution page

Guillermo Contreras (FJFI CVUT Prague)07/09/2016, 16:25Diffraction in nuclear physicsThe strong electromagnetic fields generated by ultra-relativistic heavy ions offer the possibility to study photoproduction processes at the LHC. In so called ultra-peripheral collisions (UPC), when the impact parameter of the incoming hadrons is larger than the sum of their radii, hadronic processes are strongly suppressed and only electromagenetic interactions remain. ALICE has...Go to contribution page

Jaroslav Adam (Czech Technical University in Prague, Creighton University, Omaha)07/09/2016, 16:50Diffraction in nuclear physicsUltra-relativistic heavy ions generate strong electromagnetic fields, which offer the possibility to study photon-photon, photon-nucleus and photon-proton processes at the LHC in ultra-peripheral p-Pb and Pb-Pb collisions (UPC). Exclusive photoproduction of vector mesons is sensitive to the gluon distribution of the interacting target (proton or nucleus) whereas exclusive production of...Go to contribution page

Alexander Bylinkin (Moscow Instittue of Physics and Technology)07/09/2016, 17:10Diffraction in nuclear physicsExclusive vector meson (Upsilon and Rho0) photoproduction is studied in ultra-peripheral pPb collisions at √sNN =5.02 TeV with the CMS experiment at the LHC. The cross sections are measured as a function of the photon-proton centre-of-mass energy, extending the energy range explored by H1 and ZEUS Experiments at HERA. In addition, the differential cross sections (dσ/d|t|), where|t|≈ p^2_T is...Go to contribution page
