dc.description.abstractResults on two-particle angular correlations for charged particles emitted in proton-proton collisions at center-of-mass energies of 0.9, 2.36, and 7 TeV are presented, using data collected with the CMS detector over a broad range of pseudorapidity (?) and azimuthal angle (?). Short-range correlations in ??, which are studied in minimum bias events, are characterized using a simple ?independent cluster? parametrization in order to quantify their strength (cluster size) and their extent in ? (cluster decay width). Long-range azimuthal correlations are studied differentially as a function of charged particle multiplicity and particle transverse momentum using a 980 nb?1 data set at 7 TeV. In high multiplicity events, a pronounced structure emerges in the two-dimensional correlation function for particle pairs with intermediate p T of 1?3 GeV/c, 2.0 < |??| < 4.8 and ?? ? 0. This is the first observation of such a long-range, near-side feature in two-particle correlation functions in pp or pp¯¯¯ collisions.es_ES
