Descripción
Results on two-particle angular correlations for charged particles produced in p p collisions at a center-of-mass energy of 13 TeV are presented. The data were taken with the CMS detector at the LHC and correspond to an integrated luminosity of about 270 nb-1 . The correlations are studied over a broad range of pseudorapidity (|η | <2.4 ) and over the full azimuth (ϕ ) as a function of charged particle multiplicity and transverse momentum (pT ). In high-multiplicity events, a long-range (|Δ η | >2.0 ), near-side (Δ ϕ ≈0 ) structure emerges in the two-particle Δ η -Δ ϕ correlation functions. The magnitude of the correlation exhibits a pronounced maximum in the range 1.0
