Measurement of Bose-Einstein correlations in pp collisions at √s = 0.9 and 7 TeV
Abstract
Bose-Einstein correlations between identical particles are measured in samples of proton-proton collisions at 0.9 and 7TeV centre-of-mass energies, recorded by the CMS experiment at the LHC. The signal is observed in the form of an enhancement of number of pairs of same-sign charged particles with small relative momentum. The dependence of this enhancement on kinematic and topological features of the event is studied. Anticorrelations between same-sign charged particles are observed in the region of relative momenta higher than those in the signal region.
