Multidimensional analysis of Bose-Einstein correlations in pp collisions at 2.76 and 7 TeV in CMS

Multidimensional two-particle Bose-Einstein correlation functions of charged hadrons are reported for pp collisions at 2.76 and 7 TeV in terms of different components of the pair relative momentum, extending the previous one-dimensional (1-D) analyses of CMS. This allows for investigating the extension of the source accessible to the femtoscopic correlation technique in different directions, revealing a more detailed picture of the emitting source in these collisions at increasing energies. The measurements are performed for different intervals of the pair average transverse momentum, kT , and for increasing charged particle multiplicitiy, Nch. Results in 1-D, 2-D and 3-D show a decrease of the fit radius parameters with kT , whereas a clear rise with Nch is observed in all cases. In addition, the fit radius parameters at both energies show close similarity in size and behavior within the same intervals of (Nch; kT ).
