Multidimensional analysis of Bose-Einstein correlations

Two-particle, quantum-statistical (Bose-Einstein) correlations are measured in multidimensional projections of the pair relative momentum.

Sumario:Two-particle, quantum-statistical (Bose-Einstein) correlations are measured in multidimensional projections of the pair relative momentum. The measurement extends previously performed one-dimensional studies to two- and three-dimensions for the 7 TeV data, and presents for the first time for the $\sqrt{s} = 2.76$ TeV data collected in 2013 at the CERN LHC. The measurements are performed at both energies for different intervals of the pair average momentum and for increasing charged particle multiplicity. The fit parameters corresponding to the estimated lengths of homogeneity and chaoticity parameters are presented.
