Multidimensional HBT analysis for pp @ 2.76TeV

This page describes the extraction of the signal of Bose-Einstein correlations of charged pion candidates i;e enhancement of pairs of same-charge particles with very small relative momentum from the sample of proton-proton collisions at 2.76TeV recorded by the CMS detector at LHC in 2013
