Two-particle Bose–Einstein correlations in pp collisions at √s = 0.9 and 7 TeV measured with the ATLAS detector

The paper presents studies of Bose–EinsteinCorrelations (BEC) for pairs of like-sign charged particles measured in the kinematic range p T > 100 MeV and |η| < 2.5 in proton–proton collisions at centre-of-mass energies of 0.9 and 7 TeV with the ATLAS detector at the CERN Large Hadron Co...
