Diffraction and ultraperipheral collisions at ALICE

The ALICE experiment measured J/psi photoproduction in Pb+Pb ultraperipheral collisions at sqrt(s_NN) = 2.76 TeV at forward and central rapidity. The coherent J/psi cross section is found to be in good agreement with those models which include nuclear gluon shadowing consistent with EPS09 parametriz...

Sumario:The ALICE experiment measured J/psi photoproduction in Pb+Pb ultraperipheral collisions at sqrt(s_NN) = 2.76 TeV at forward and central rapidity. The coherent J/psi cross section is found to be in good agreement with those models which include nuclear gluon shadowing consistent with EPS09 parametrization. Results on rho_0 photoproduction in ultra-peripheral Pb+Pb collisions are also briefly discussed. Studies on exclusive J/psi in p+Pb and on diffraction in pp collisions are mentioned.
