Measurement of the Cross Section for Electromagnetic Dissociation with Neutron Emission in Pb-Pb Collisions at √s_NN=2.76 TeV

Abstract

The first measurement of neutron emission in electromagnetic dissociation of 208^Pb nuclei at the LHC is presented. The measurement is performed using the neutron zero degree calorimeters of the ALICE experiment, which detect neutral particles close to beam rapidity. The measured cross sections of single and mutual electromagnetic dissociation of Pb nuclei at √s_NN=2.76 TeV with neutron emission are sigma_singleEMD=187.4 +-0.2 (stat) +13.2-11-2 (syst) b and sigma_mutualEMD= 5.7 +-0.1 (stat) +-0.4 (syst) b, respectively. The experimental results are compared to the predictions from a relativistic electromagnetic dissociation model.
