Principal-component analysis of two-particle azimuthal correlations in PbPb and pPb collisions at CMS

For the first time a principle-component analysis is used to separate out different orthogonal modes of the two-particle correlation matrix from heavy ion collisions. The analysis uses data from √ s

Multi-particle azimuthal correlations in p-Pb and Pb-Pb collisions at the LHC

Measurements of multi-particle azimuthal correlations (c umulants) for charged particles in p-Pb at √ sNN = 5.02 TeV and Pb-Pb at √ sNN = 2.76 TeV collisions are presented. They help address a

Probing novel long-range correlation phenomena in pPb collisions with identified particles at CMS

Observation of a long-range near-side two-particle correlation (known as the ”Ridge”) in high-multiplicity pp and pPb collisions opened up new opportunities of exploring novel QCD dynamics in small

Correlations between jets and charged particles in PbPb and pp collisions at $\sqrt s_{NN}$= 2.76 TeV

The quark-gluon plasma is studied via medium-induced changes to correlations between jets and charged particles in PbPb collisions compared to pp reference data. This analysis uses data sets from

Measurements of azimuthal anisotropy and charged-particle multiplicity in d + Au collisions at √sNN=200, 62.4, 39, and 19.6 GeV

We present measurements of the elliptic flow (v2) as a function of transverse momentum (pT), pseudorapidity (η), and centrality in d+Au collisions at sNN=200, 62.4, 39, and 19.6 GeV. The beam-energy

This note describes several methods for measuring the efficiency to reconstruct charged particles in the inner tracker of the CMS detector at the CERN Large Hadron Collider. The first method obtains

System size dependence of cluster properties from two-particle angular correlations in Cu+Cu and Au+Au collisions at $\sqrt{s_{_{NN}}}$ = 200 GeV

We present results on two-particle angular correlations in Cu+Cu and Au+Au collisions at a center-of-mass energy per nucleon pair of 200 GeV over a broad range of pseudorapidity (eta) and azimuthal

Differential measurements of charged particle azimuthal anisotropy are presented for lead-lead collisions at root sNN = 2.76 TeV with the ATLAS detector at the LHC, based on an integrated luminosity

Decomposition of harmonic and jet contributions to particle-pair correlations at ultrarelativistic energies

Methodology is presented for analysis of two-particle azimuthal angle correlation functions obtained in collisions at ultrarelativistic energies. We show that harmonic and di-jet contributions to

Jet cross sections can be in principle compared to simple pQCD calculations, based on the hypothesis of factorization. But often it is useful or even necessary to not only compute the production rate

Results 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

Collision-geometry fluctuations and triangular flow in heavy-ion collisions

We introduce the concepts of participant triangularity and triangular flow in heavy-ion collisions, analogous to the definitions of participant eccentricity and elliptic flow. The participant
